Best 7 File Sync Software Tools in 2026: Compare Plans and Ease of Use

Introduction

Dropbox is the strongest overall pick for file sync software, with broad cross-device syncing and useful features for business teams. This roundup compares seven tools for different needs, including syncing everyday devices, managing NAS storage, handling client document workflows, and moving business data across core, cloud, and edge environments.

Quick comparison

Platform support varies, so check that a tool works with your devices and storage setup. The reviews below cover where each one fits.

1. Dropbox

Best for: General-purpose file syncing across personal and team devices.

Dropbox syncs files and folders across computers and mobile devices, making it easy to keep everyday work available in more than one place. Support for a wide range of devices is useful for teams that use different operating systems.

Business plans include team folders and administrative controls, so Dropbox can handle more than individual file access. Choose it for a familiar cross-device setup with team features. If you need NAS management or specialized client workflows, another tool may be a better fit.

2. ShareFile

Best for: Businesses that handle client documents and file exchange.

ShareFile combines file syncing and sharing with tools for collecting documents, creating client portals, and handling e-signatures. Audit logs help teams track document activity.

Its main strength is the client-facing document process. Clients can exchange files with a business through more than a basic shared folder. ShareFile is worth considering if collecting and sharing documents is part of regular client work, rather than just a way to keep staff devices in sync.

3. GoodSync

Best for: Syncing across mixed devices, storage systems, and cloud services.

GoodSync supports computers and mobile devices, along with NAS systems, cloud storage, and network file systems. That range is useful when files live across several types of storage instead of in one cloud account.

GoodSync connects to services including Google Drive, Dropbox, OneDrive, and SharePoint. Those integrations are helpful for teams working with multiple destinations. Before settling on a sync plan, check that it supports the specific devices and services you use.

4. ownCloud

Best for: Teams seeking an open-source file collaboration option.

ownCloud lets teams sync and share files, then access and work with them across devices. Its open-source approach sets it apart for organizations considering alternatives to conventional hosted file-sync services.

ownCloud may suit teams that want more control over their collaboration setup. The right deployment depends on their needs and technical environment, though. Review the available options and compatibility details before deciding how it fits with your storage and team workflows.

5. Resilio Connect

Best for: Business file movement across core, cloud, and edge environments.

Resilio Connect is designed to synchronize and move business data across core, cloud, and edge environments. It’s a more specialized option than a basic tool for keeping personal devices in sync.

Its main strength is support for distributed environments, where data may need to move between different parts of a business setup. Consider it if that’s the problem you need to solve. For everyday team folders, a general-purpose sync product may be a better match.

6. Egnyte

Best for: Business users who want desktop access to Egnyte content.

Egnyte supports desktop workflows for accessing, syncing, and sharing business files. Users can work with Egnyte content from their desktop instead of relying only on a browser.

Its main draw is desktop access to business content. Egnyte is worth comparing if your team already uses its content environment and wants file access and sharing built into desktop work. Check that the desktop setup supports your devices and fits the way your team works.

7. Synology Cloud Sync

Best for: Syncing files between a Synology NAS and other storage.

Synology Cloud Sync connects a Synology NAS to public cloud or on-premises storage. You can set the sync direction, schedule, and folders, giving administrators control over what moves and when.

Those controls are its main advantage. Teams can choose specific folders and decide when synchronization runs, rather than treating the NAS as a simple mirror of every destination. It’s most relevant if a Synology NAS is already part of your storage setup.

How we picked these tools

We focused on products where file synchronization is a core use, rather than an add-on to general file storage. The comparison looks at the devices and storage destinations each provider supports, as well as business workflows such as team administration, client document exchange, and distributed data movement.

The list covers setups ranging from individual device syncing to NAS-based storage and business environments spanning core, cloud, and edge. These tools aren’t interchangeable, and no single option will suit every team. Before choosing, check current plan details, supported platforms, and compatibility with your storage destinations.

Frequently asked questions

File sync software keeps files consistent across supported devices or storage locations by applying changes between them. Syncing isn’t automatically the same as backing up: a deletion or edit may carry over to other locations. Check separately whether you need recoverable historical copies.

For business use, compare device support, sharing features, administrative controls, and compatible storage destinations. Not every tool requires a NAS or cloud account. Requirements depend on the product and how you plan to use it.

What should I look for in file sync software?

Check that the software supports the platforms and storage destinations your team already uses. Then compare its sharing, team administration, and client workflow features with what you need. If you have a specific setup in mind, make sure its sync direction, schedule, and folder controls will work for you.

Is file syncing the same as backing up files?

No. Syncing carries changes between locations, while backup is meant to preserve copies you can recover. Deleting or changing a synced file may affect other synced locations, so assess your backup and version-history needs separately.

Can file sync software work with a NAS?

NAS support depends on the product and configuration. GoodSync and Synology Cloud Sync both support NAS-related syncing in different setups. Check compatibility with your NAS and cloud service, as well as the sync direction you need.

The verdict

Dropbox is the strongest overall pick for broad cross-device syncing, with business team folders and administrative controls. GoodSync is a strong runner-up for setups spanning devices, NAS systems, and cloud services. If your team already uses a Synology NAS, Synology Cloud Sync offers configurable syncing with cloud or on-premises storage. Choose based on your storage setup and workflow.
