I would doubt that it's much (if any) different from the official release(s). But maybe someone disassembled or patched something. > That includes its own lfn option, what specifically is dos lfn? Win95 added an API for longer filenames up to 255 chars. (DJGPP 2.0 [GCC for DOS using DPMI] supported those out of the box.) Normally DOS is restricted to 8.3, which many people (including developers) still find restrictive. But so-called "long file names" (LFNs) only work under the Win95 GUI, not under MS-DOS 7 proper. DOSLFN.COM is a TSR that allows real DOS (like FreeDOS) to create and find such "long file names" in a compatible way. (It's some weird hack where DOS misuses the volume attribute for separate pieces of the file name.) HPFS from OS/2 was an improved file system (i.e. better than FAT), so I always dreamed that FreeDOS would support it. But despite supporting LFNs and being more efficient, you're still limited to 2 GB max file size, and it's not journaled (thus still needing periodic file system checks upon improper shutdown), so people weren't majorly interested. Not enough of an improvement, I guess. (FreeBSD used to support it, but I don't know if they ever added it back after making their file system code reentrant.) Apparently OS/2 eventually moved to JFS (journaled file system) to overcome such limitations. _______________________________________________ Freedos-user mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/freedos-user
