iFolder synchronizes individual files or the changed portions of individual files; it does not synchronize files as a set. If you have a database file that is implemented as a collection of linked files, do not try to synchronize them in an iFolder.
Do not try to synchronize your GroupWise® data by making the GroupWise archive, cache, or remote directories into iFolders. If you do this, the GroupWise data files become corrupted after synchronizing the file a few times. GroupWise needs the files in the archive to be maintained as a set of files.
