Zusammenfassung:A file system for a computer supports a plurality of directories, each maintaining a list of data files as a plurality of directory entries. As well as means for creating data entries for real data files, the system includes means for creating anti-file directory entries having an attribute indicating there is no real data file corresponding to the entry. Entries may-be moved between directories and when an anti-file and a data file of the same name are present in the same directory, the real data file is deleted. This enables the synchronization of sets of target and source files to take account of changes.
