FreeFileSync is a simple software program that allows you to synchronize or compare two folders. It can be mainly handled by users with some experience in this area.
This tool can also be installed as a portable product. In this case, you can store FreeFileSync on a USB flash drive or any other removable device, save it to any computer and directly run its executable file.
Therefore, you can always carry FreeFileSync with you when you're on the more. What's more important is that the Windows Registry is not updated with new entries, and no leftover files can be found on the hard drive after program removal.
The interface of the application is user-friendly. So, you can add as many folders to the list as you want, by using either the file browser or 'drag and drop' method.
Comparing them can be easily done, with the click of a button. FreeFileSync allows you to pick one of two modes for the comparison procedure, by file time and size, or by file content.
In addition, you may choose a variant for the synchronization mode, between 'two way' and 'mirror'. Plus, you can make FreeFileSync ignore all errors dialogs which pop up, send files to the Recycle Bin or permanently remove them from the system when deleting items, configure filters, as well as save the configuration settings for future projects; the file list can be exported to file.
FreeFileSync supports multiple languages for the interface, has a good response time, and includes user documentation. We have not come across any issues throughout our testing; FreeFileSync did not freeze, crash or pop up error dialogs. First-time users may take a while to get accustomed to the layout; the interface could had been better organized.
