EN FreeFileSync: review, download and setup
Compare folders and preview changes before running two-way sync or mirroring in FreeFileSync.
What is FreeFileSync used for?
FreeFileSync compares folders and shows a plan to copy, update, and delete files. It is useful for transferring data to another disk and maintaining agreed copies. The synchronization mode is selected for a specific task.
Bilateral synchronization and mirror vary. In mirror mode, the purpose contents are given to the source, including possible deletions. Before launch, you need to check the direction, and not focus only on familiar names of folders.

Review the comparison before writing changes
Specify two test folders and perform a comparison first. Look at the action icons and the deletion list. Filters can exclude part of the files, so the absence of action does not mean the complete match of directories.
For regular work, save a clear configuration. If you need a change history, set up a suitable option for storing deleted or replaced files. Periodically check the recovery, not just the successful completion of the task.

Can I see the changes first?
Oh, yeah. The comparison shows the intended actions before synchronization.
Is it an encryption tool?
