Recover Overwritten Files

By default, SyncToy never deletes or overwrites any files. Instead, it moves the files to the system Recycle Bin. Should you need to do so, you can recover these files from the Recycle Bin and copy them wherever you like.

Note that you can change SyncToy's default behavior by changing the setting for "Save overwritten files in the Recycle Bin" on the SyncToy options screen. Turning this option off will cause SyncToy to delete these files permanently rather than storing them in the Recycle Bin. Turning this option off causes SyncToy to use less disk space, but it makes it impossible to recover any overwritten or deleted files that you might want in the future.
