How to choose

Which platforms does it need to run on?

Start with the devices and operating systems you use. The comparison covers Windows, macOS, Linux, Android, iOS and web support.

Check the supported-platform details for the tools you are considering, especially if you need files to stay in sync across different kinds of devices.

Which sync method do I need?

Compare the listed sync method with how you want files to move between your devices or services. The board includes sync method as a comparison field.

If the method is not clear from a tool’s details, confirm it before choosing.

Do I need selective sync or version history?

Selective sync lets you consider whether you can choose which files or folders sync. Version history is worth checking if you need access to earlier file versions.

Compare both fields against the way you plan to manage files; availability can differ by tool.

What file size and encryption details should I check?

Check the maximum file size against the files you need to sync, and review whether encryption at rest is listed. Encryption at rest means protecting stored files while they are not being transferred.

If either detail matters to your choice, confirm it for the plan you intend to use.

Can I try it before paying?

Compare the free-plan mark, any free trial, and the paid starting price. A free plan and a time-limited trial are different offers.

For example, ChronoSync and Insync list 15-day trials with paid starting prices; FreeFileSync lists a free plan and paid pricing from €20.

Questions

What does file sync software do?

It keeps files in sync across supported devices or services. Compare sync method, platforms, selective sync and version history to find a fit.

How do I choose file sync software for my devices?

Check that it supports the platforms you use, then compare its sync method and file-management options.

Is file sync software free?

Some tools list a free plan, while others are paid or offer a free trial. Check the plan and price details before choosing.

What is selective sync?

It is a comparison field for file sync tools. Check a tool’s details to see whether it offers selective sync and whether that suits your needs.

Compare encryption at rest and maximum file size. Confirm both details for the plan you expect to use.
