1. Microsoft OneDrive

Free 5GB storage

Real-time collaboration

Personal Vault

OneDrive is Microsoft’s default cloud storage tool that also works as a data mirroring software for various devices. We’re talking desktops, tablets, smartphones – anything that can sync data with the cloud. 

Here, you can simply upload any file, then edit and access it on any connected unit. It’s a cross-platform tool that synchronizes between your Windows, macOS, Android, and iOS devices.

As such, real-time group editing is a breeze on this program. 

You can contribute photos or documents with other users for live collaboration. With the Share button, you invite people to work on the cloud. Or, you can generate a link and then send it to them via email or text. Just keep in mind that users must be working within the MS ecosystem.

Additionally, you can back up certain locations from your computer to OneDrive – thanks to the auto folder sync feature. With it, you can run an automatic backup of files stored in specific folders like Documents, Pictures, Downloads, etc. This is particularly handy for Windows users since OneDrive comes pre-installed in the operating system.

Another great tool you can use for security is the Personal Vault. It appears alongside your regular folders as such: 

best file sync software Microsoft OneDrive interface

This is where you can store your confidential documents, photos, and other media. It’s extra safe because it requires an authentication method like a passcode, fingerprint, or SMS code. You can also sync this vault, so it’s accessible anywhere. Unfortunately, this feature is only available in Windows.

Now, do these features come at a high price?

Yes and no. On the basic version, you get 5 GB of storage for free. If you need more space, you can upgrade to 100 GB of storage for $20 annually

As a standalone app, the price is quite steep. We recommend investing in the MS sync software if you regularly and collaboratively use MS tools like Word, Excel, or Powerpoint.

2. Sync.com

End-to-end encryption

Third-party file access


With a name as straightforward as Sync.com, you can’t go wrong. This free file sync software lets you access your computer files on any device with a cloud connection. But that’s pretty basic, isn’t it?

What makes this tool truly shine is its inner workings. 

First off, it has robust security for its data synchronization processes. It is zero-knowledge compliant, meaning only you can access information on the platform. And it uses AES 256-bit encryption and the TLS protocol to protect file transfers from cyberattacks

You can also set up a two-factor authentication method on this cloud sync software.

While it has basic tools for collaboration, you can still take advantage of its third-party integrations. For example, you can view and edit MS Office documents or PDFs without leaving the interface.

Another helpful feature here is file versioning. When you get hit by malware or ransomware and lose your files, it’s not the end of the world! Upon enabling the cloud sync, the software will auto save versions of edited and deleted files for at least 30 days. And get this, it doesn’t use your storage quota. 

The program is free of charge but with limited functionality. You get more with a premium subscription, and here’s a quick comparison:

  • Free - 5 GB storage
  • Basic - $8/month, billed annually. Includes 2 TB storage and advanced sharing
  • Professional - $24/month. Includes 6 TB storage and custom branding

There’s a separate paid tier for teams, starting at $5/month/user.

The downside to this pricing structure is the lack of a monthly payment option for the Basic version. If you intend to use this plan for only a short period, you have no choice but to pay for an annual subscription.

But among many similar tools on the market, we’d say Sync.com is the best sync app worthy of commitment.

3. GoodSync

Block-level sync

Inter-cloud transfers

Version history control

From your desktop, you can have one-way or two-way data synchronization across various locations and platforms. It’s one of our top picks for Mac and Windows file syncing, and here’s why.

It provides block-level data transfers, which basically translates to micro-updates. When you make changes to a document, the program updates that specific portion only instead of the whole file. This, in turn, speeds up the backup time, lessens the storage requirements, and eases your bandwidth usage.

The interface looks a little dated, but some automated functions make up for that. 

One redeeming quality is that it automatically detects file edits, ticking the box for real-time file synchronization. Additionally, it can identify file and folder re-names and execute them as Move commands. It can also run scheduled backups and syncs to save time.

Our favorite feature is that it integrates well with third-party cloud syncing software. This allows you to transfer files or folders to and from other cloud storage providers like OneDrive or Google Drive. You can only do this on the desktop app.

In terms of security, the tool meets industry standards. It uses reliable AES 256-bit encryption for stored and in-transit files. Users are also free to create encryption keys, but this requires some manual effort.

Great news - GoodSync has a free version that lets you sync up to 100 files.

If that’s not enough, for $29.55, you can purchase a one-year license of this file sync utility

Alternatively, you can opt for in-house cloud storage with 10 GB of space, which costs $10 per year.

Despite this huge gap in the pricing tier, it’s still a wise choice for personal or business use. Give GoodSync consideration if you need auto synchronization software that works fast and well with other cloud storage.

4. Dropbox

Safe and secure

MS Office and G Suite integration

Accessible version history

Dropbox is one of the first cloud storage solutions, and its features have remained far superior to others since 2008. If hunting for free file synchronization, this software is right up your alley. 

It provides a solid platform for keeping your files stored, updated, and accessible on any device – without cost. You get 2 GB of storage for free and handy syncing tools that help keep you organized and safe.

Let’s first tackle the safety aspect.

Dropbox integrates several layers of security into its processes. With AES 256-bit standard encryption, each file transits with SSL/TLS protocols. In addition, users can employ a two-factor authentication method for extra login security.

It’s unclear, however, whether or not the program provides zero-knowledge encryption.

With similar specs, it’s hard not to compare it to OneDrive and Google Drive. The big difference is that those two have native productivity tools that work well with computer sync software. 

To keep up, Dropbox allows integrations for these platforms. You can create, edit, and share MS Office or Google Workspace documents within the program. And it helps that the interface is capable of real-time sync and collaboration.

The best part? You can send password-protected files to other users for bolstered security. You can even monitor how many times they view, edit, or download the transferred file.

If you’re worried about file recovery, don’t. You can restore deleted files and access version history for 180 days.

If 2 GB isn’t enough for you, you can opt for more space. Here are the storage plans:

  • Plus - $12/month (2 TB, one user)
  • Family - $20/month (2 TB, six users)
  • Business - starts at $16.58 when billed annually (3 TB, one user)

Clearly, it’s not the cheapest file sync app you’ll find. But against other free solutions, Dropbox is tough to beat.

5. Files.com

Numerous integrations

Transfer automation tools

Functional mobile apps

Files.com doesn’t compete with top cloud syncing software. Instead, it works with them. It isn’t called a Transfer Automation and Integration Platform for nothing!

The tool welcomes a slew of third-party integrations that make file synchronization more efficient. You can partner it with:

  • Google Cloud
  • Microsoft Azure
  • Dropbox
  • Amazon S3
  • Backblaze

And so many more.

To get things going, you can configure specific sync jobs for designated remote places. You can push files to the remote location or pull files from it. You’re also free to mount the remote server for live direct access, but this part can be tricky. It’s one of those sync tools that will take some getting-used-to.

In addition, you can use Microsoft Office apps like Word, Excel, and PowerPoint directly from the Files.com website. A bonus feature is that you get clear previews and real-time collaborative editing on any type of document. And sending files to team members is a breeze.

But can you share synced files with external clients? Absolutely. 

You can send them via email containing downloadable web links. For security, you can password-protect the documents, set expiry dates, or limit the number of downloads. You can also opt for a single sign-on (SSO) setting or employ multi-factor authentication methods.

You can do all these things on the desktop app for Windows and macOS. And on the mobile apps for iOS and Android, you get full access to all your synced files and workflows. 

Now, the price.

Files.com doesn’t have a pricing structure listed on the website. Instead, you must request a quote for the service. It isn’t a free syncing program either. You can expect the average Starter plan to cost around $100 per month, making it a suitable option for businesses.

6. Resilio

P2P file sharing

Lightning-fast speeds

Automatic transfers

Unlike most solutions we’ve reviewed, Resilio doesn’t take the form of a cloud sync software

Instead, it uses peer-to-peer (P2P) technology to transfer files to multiple destinations. P2P file transfers are 2-10x faster than other solutions. They are also free from issues related to cloud-based file synchronization

best file sync software Resilio File sync method

So, you can rest assured that all files are 100% private and inaccessible to other P2P file-sharing services.

This file sync service stands out because of its lightning-fast speeds, even when syncing large files. You can synchronize photos, videos, PDFs, or other file types to and from your mobile phone, laptop, or network-attached storage (NAS).

That’s why it’s versatile and supports all operating systems, including Linux. Remember, Resilio must be installed on every device for it to work.

You can sync all computer files and folders at once or individually. It has a Selective Sync feature that creates placeholder files in the system, which you can search locally. With this, you can download only the files you require. No need to replicate entire folders on each device!

And, of course, what completes a data sync software is that extra layer of security. When sharing files, you can protect them with two-factor authentication. You can also limit the people who can access by putting permissions on documents. Like Files.com, you can set an expiration date to your web links. 

And the best part, there are no cloud or third-party servers involved. Just your information on your devices!

As for the price, Resilio has a free version, but it lacks Windows Server Support. For full functionality, it offers one-off and subscription-based options:

  • Sync Home - $59.90 (one-time)
  • Sync Family - $99.90 (one-time, up to 5 users)

There’s a separate paid tier for Businesses which starts at $6/user/month for 5-15 members. If you have a bigger group, you can consider Resilio Connect - its computer syncing software for enterprises.

Best for: Collaborations

7. Egnyte Sync

MS and G Suite support

Solid file security

Live collaborations

Egnyte is a trusty Mac and Windows file sync solution loaded with essentials. 

At the base level, it ensures that every file you upload into the platform is in sync across all devices. And the good thing is, these files don’t take up space on your PC.

One notable feature of this tool is its native support for Microsoft Office and G Suite. As such, real-time synchronization with other productivity apps is swift! The WebEdit tool also makes it quick for users to work on the same file within the website.

Additionally, you can create private collaborative spaces for specific users. Admins can add unlimited subfolders, control user access, and edit all data.

But what else separates Egnyte from other synchronization software?

It has a storage sync feature, which allows you to share your local storage to the cloud.

Another is the ability to set specific roles and control access when transferring files. It has similar link sharing and file requests settings for Google Drive. The difference, admins can control the type of link that users can generate and other actions.

What about security? The program uploads data encrypted with AES 256-bit and transferred over an SSL/TLS protocol. Egnyte, however, is the one managing the encryption keys. If you want complete control in that department, you will have to subscribe to its Enterprise plan.

Speaking of plans, the file sync tool offers straightforward pricing. A Business plan will cost you $20/user/month, paid annually. This provides 20 GB of storage with ten employee licenses.

Enterprise Lite and Enterprise – have custom prices for bigger teams.

And while OneDrive and Sync.com offer more storage for less, Egnyte makes up for it in functionality.

8. Syncplicity

Online-only storage

Microsoft 365 integration

File version history

The name says it all – Syncplicity offers a simple yet effective solution to cloud-based syncing, sharing, and collaboration.

When you download the file synchronization software, it creates a network drive that hosts your computer files. Providing online storage, it saves space on your hard drive. Like OneDrive, you get to store specific files in the cloud while others stay on your PC.

Another key feature is its native Microsoft Office 365 integration. You can collaborate with MS users in real-time and share your files via Outlook.

Syncplicity also allows file versioning. You can restore previous versions as well as deleted files. But unlike Sync.com, these file versions, including the trash bin, count against your storage quota.

And while it’s an excellent folder sync software, it’s not so handy when it comes to sharing. Unlike other solutions, it doesn’t allow link-sharing for folders and sub-folders but only for individual files.

Another weak point is its upload and download speeds. It can take a while to transfer and sync large files.

Block-level synchronization could solve this, but Syncplicity lacks this. It transfers the entire file for every sync, resulting in sluggish speeds. 

But on the bright side, it checks all the boxes in terms of security. It uses AES 256-bit encryption and TLS tunneling for max protection. Admins can also employ two-factor authentication, single-sign-on settings, and password protection.

So, how much is this file replication software?

There’s a free Personal edition with 10 GB of storage. And, if you need more, here are your options:

  • Paid Personal - $5/month (100 GB)
  • Business - $5/month/user (300 GB)
  • Enterprise - Custom price

You can try these out with its 30-day free trial.

Best for: Mac

9. Apple iCloud Drive

Affordable paid tier

Automatic syncing

Easy file sharing

If you’re an Apple user, the best Mac sync software is the one you already have – iCloud Drive.

This cloud storage platform comes pre-installed on your iPhone, iPad, and Mac. Aside from storing files, it also keeps all your files and folders up to date across multiple locations – even your Windows PC. All you have to do is sign in to your iCloud account on all connected devices. The synchronization will run automatically.

Folder sync is enabled, too. On your Mac, you can simply add your Desktop or Documents folders to the Drive to enjoy anywhere access.

When running a file sync on the cloud, you lose access to previous versions. Unlike Syncplicity or Sync.com, it has no file versioning feature. You can recover deleted files from the Trash within 30 days, but other than that, there are few restoration options.

Security-wise, Apple encrypts the Drive data, which is good. But unlike other solutions on our list, it doesn’t use end-to-end encryption. Fortunately, you can add two-factor authentication for added protection.

Now, the price tag.

All users receive 5 GB of storage for free, but this will likely run out quickly if you plan to sync all your files, including photos and videos. For additional space, here’s what Apple offers: 

  • 50 GB - $0.99/month
  • 200 Gb - $2.99/month
  • 2 TB - $9.99/month

If you simply want an automated file sync solution, it’s worth your while. But if you need advanced features, you can consider other similarly priced tools, like OneDrive or Sync.com.

Best for: Google Workspace users

10. Google Drive

Free 15 GB storage

File versioning

Google Workspace integration

Google Drive is a syncing software and cloud storage popularly used. It’s free and readily available, making it an easy choice for personal and professional use.

Its core function is simple – storing data and making it accessible virtually anywhere. With a Google account and an Internet connection, you can view, edit, and share your files on any platform. 

Thanks to real-time synchronization, collaborators can work on a single document simultaneously. And on the paid versions, you get a Team Drive setting that lets admins have more control over user access and actions.

Although each file sync in the cloud is encrypted, Google doesn’t provide end-to-end encryption. As a result, your sensitive data may get exposed to malicious activities or cyberattacks. However, it offers strict two-factor authentication bolstering its file security.

The most significant advantage here is the number of tools you can use with Drive. These include Docs, Sheets, Slides, and more. You can also integrate Microsoft Office documents onto the platform.

Google Drive provides 15 GB of free storage, comparatively larger than others. But it’s worth noting that the storage encompasses the entire G Suite. And if you plan to use Google Photos, this won’t take you far.

You can get more out of this software by getting a Business Standard subscription that costs $12/user/month for 2 TB worth of storage space.

What Is File Syncing?

In computing, file synchronization is the process of keeping multiple files in various locations up to date. Typically, cloud storage providers come with enabling features. But now, there are dedicated computer sync software offering this solution, such as Sync.com and GoodSync.

So, how does it work?

These tools auto-save copies of your local data in real-time. This way, you can access your files even as you make changes to them on the fly.

There are two types of file synchronization – one-way and two-way. 

In a one-way file sync, data updates to numerous target destinations and platforms from a single source. However, no data is stored back at the source. 

On the other hand, a two-way file share updates the data in both directions. For example, when you delete a file in a cloud storage medium, the local file in the source will be deleted too.

File sync software is essential for individuals wanting anywhere-access to their important files. Businesses also have become reliant on file synchronization to support collaboration.

How to Pick The Right Solution For You

Finding the best software in a sea of excellent options is no easy feat. But we’re here to help.

Consider the following when deciding on the right tool.

Multi-platform Support

Among other things, the true essence of this program is anywhere access. So, the solution must be compatible with most kinds of file destinations. That includes devices, operating systems, network-attached storages (NSAs), and whatnot.

For example, if you run a file sync on Windows 10, you should be able to access the synced files on a Linux device or a smartphone.

Real-time Sync

Good platforms can reflect file changes instantly. This will enable you to access your files on any connected device consistently. This also allows for a smooth and systematic workflow for collaborations. Thankfully, all solutions on our list check this box.


The potential risk with consumer-grade file sync services is that your data might get breached, lost, or stolen. As much as possible, auto-sync software should offer a zero-knowledge policy to its users - guaranteeing the service complies with data protection and privacy laws.

Cloud security is also an essential feature to look for. This includes but is not limited to encrypted file sharing, preferably with the industry norm, AES 256-bit encryption. Using SSL/TLS protocols is also key to protecting files in transit.

Lastly, having a two-factor authentication method at the admin level will ensure that no one but you can log into your account.


You don’t have to spend a lot of cash to enjoy the benefits of file synchronization. Free file sync software like OneDrive, Sync.com, GoodSync, Resilio, and Google Drive offer great services without any costs. 

It all boils down to the kind of security, functionality, and storage size you need.

Wrap Up

Syncing your files may seem challenging, but it couldn't get any simpler than with the best file sync software.

Each solution on our list eliminates the hassle of manually copying, saving, or backing up your files.

And they keep your data safe and secure, too!

So – which one will you get your hands on?
