LFNDOS provides the Windows95 Long Filename (LFN) API to DOS programs. It uses the same format for storing the names on disk as Windows95 does, so you can view and use long filenames under both systems interchangeably. It runs as a memory-resident program, and while resident requires about 60k of conventional memory.

Under Windows95, a DOS program can use long filenames by calling a set of interrupt functions, which Windows provides. For example, COMMAND.COM will allow long filenames when run as a DOS Prompt from Windows, but not if you restart in MS-DOS mode. Other programs such as EDIT.COM and all DJGPP programs use long filenames if available.
