Detect Moved Files
FreeFileSync is able to detect moved files on one side and can quickly apply the same move on the target side during
synchronization instead of a slow copy and delete. To make this work, FreeFileSync requires database files
to compare the current file system state against the time of the last synchronization.
The Two way
variant already creates database files, therefore, detection of moved files is always active.
variant however, does not need the database files to find synchronization directions, so detection of moved files
is not available by default. If you don't mind the creation of the database files, you can enable this feature by
selecting the Detect moved files
- Detection of moved files is not yet possible when synchronizing a folder pair for the first time. Only beginning with the second sync
the database files are available to determine moved files.
- Detection is not supported by all file systems. Most notably, certain file moves on the FAT file system cannot be detected.
Also virtualized file systems, e.g. a mounted WebDAV drive, might not support move detection. In these cases FreeFileSync will automatically fall back to copy and delete.
