File sync refers to the process of copying files from one location to another or from one device to another.

There are many situations when file sync is needed:

  • Sync files between computers so that you have the same files on different computers.
  • Sync files to an external drive so as to make a backup for your important files.
  • Sync local files to the cloud so you can access your files anytime and anywhere.

Due to the great demand for file sync, plenty of file sync software appears. In this article, I’ll introduce the 5 best Windows file sync software to you.

Top 5 Windows File Sync Software – Free To Use

Following is the list of the best windows file sync software that you might need to know before getting started.

  1. FreeFileSync

FreeFileSync is a free and open-source file sync tool available for Windows, macOS, and Linux. It works by comparing one or multiple folders on their content, date, or file size and subsequently synchronizing the content based on your settings. There are four sync modes you can choose from; Two Way, Mirror, Update, and Custom.

  • Two Way: sync changes not only from the left folder to the right folder but also the other way around.
  • Mirror: create a mirror backup of the left folder by adapting the right folder to match.
  • Update: copy new and updated files to the right folder. If you delete files in the left folder, they won’t be deleted in the right folder.
  • Custom: configure your own synchronization rules.

Apart from the features mentioned above, FreeFileSync allows you to create a batch job to run file sync without entering the main window of the program. To schedule a sync task to run automatically, you need to resort to your operating system’s scheduler, such as Windows Task Scheduler and macOS Automator, and Calendar
