12 Best Free File Sync Software for Windows and Mac

The advent of technology has paved the way for a lot of new stuff and has re-shaped how we do many things. These days, for one reason or another, you may want to have the same file or document available and accessible on your multiple devices; this is where these best free file sync softwares come into play. They help you process the duplication of your files and settings across multiple devices by “synchronizing” your files in these systems or devices.

What is File Syncing?

Well, file syncing is the process of “synchronizing” your files across multiple systems or storage-enabled electronic devices. To better understand what “File Syncing” means, you’d need to understand what the term “Synchronization” means. Synchronization simply means to make data or a number of files to be “the same” in different devices or storage location. That said, “File Syncing” refers to the computing process of making some set of data or files to appear in different storage devices without being altered.

File syncing also means that one can access exactly the same file on different systems. The syncing is updated by specific rules and in real-time; thus, there are two major types of file syncing; one-way file synchronization (mirroring) and two-way file synchronization.

However, regardless of the types, file syncing sees that “File A” on System 1 is exactly the same as the “File A” on System 2, and when the file is updated on System 1, it automatically updates on System 2, ensuring that both systems have the same data – that’s practically what file syncing does.
