GoodSync is sold in 5-license sets, so you can mix and match platforms with a great deal of flexibility. There are many other excellent sync tools out there, but GoodSync distinguishes itself by running on MacOS, Linux, Windows, iOS, Android, and even some NAS boxes. Our pick for the best multi-platform sync tool is GoodSync.

Sync tools can often be used in a one-way sync, and when that happens, they also remove files from the destination directory if they've been removed from the source directory. But the key is finding files that are supposed to be moved and moving them. Most sync apps add to that, allowing for backups, test runs, etc. The raison d'etre of a good sync tool is keeping two directories in sync, making them identical.
