From PC Exchange 2.1 onwards, they store the Mac OS long filenames as standard FAT long filenames and convert FAT filenames longer than 31 characters to unique 31-character filenames, which can then be made visible to Macintosh applications.

If enabled, the virtual filenames (VFN) are available under separate logical drive letters, whereas the real filenames (RFN) remain available under the original drive letters.

In order to support Java applications, the FlexOS -based IBM 4690 OS version 2 introduced its own virtual file system (VFS) architecture to store long filenames in the FAT file system in a backwards compatible fashion.

In Unix filesystems, filenames are usually case-sensitive.

Mac OS using PC Exchange stores its various dates, file attributes and long filenames in a hidden file called " FINDER.
