Q. It appears that SyncToy does not synchronize certain system files. Is this expected?
A. The only system files that SyncToy 2.0 does not synchronize are the Thumbs.db and Desktop.ini files and then only if these files are marked with the System AND Hidden attributes. This was a specific feature request we received from many users of SyncToy 1.4 and it seems to provide a better user experience because these two system files are local settings/cache files that do not make sense to replicate to the destination folder.
