This program copies new file entries in both directions and in any new folders that may be created.
The old folders will not be entirely replaced by the new, but their contents will be updated with the newest files, entries and folders.
If a conflict occurs between file names and folder names, the program will append the suffix to the file names. It can also switch into a backup program.
With the newest version, you can exclude up to 16 folders. The program supports root privileges, and it can auto-mount volumes automatically.
