Title: DMS and RUN files??
Post by: on March 27, 2003, 02:24:35 AM
I got some drivers for my Supra 500xp but they are in DMS and RUN files. What do I do with these?

DMS files are images of entire floppy disks, like adf files, except they are compressed and aren't as big. There are utilities to extract them. RUN files are executable files. You probably run them in a CLI window.

Yeppers - DMS was used to pack an entire floppy disk into a single compressed file (like Lha compresses a bunch of files into a single archive).

If you need to get a DMS back to a floppy, but have no Amiga floppy drive (for whatever reason) - do a search on Aminet for FMS or a similar virtual floppy system - you can unpack and mount it that way.

Siggy.

DMS stands for Disk Mashing System. It's a way of archiving and compressing a whole AmigaDOS floppy disk, usually for transport over wire. There's utilities on Aminet to UnDMS archives, and mentioned above is FMS which can be used to mount "virtual" floppy drives. Simply install FMS, give it a place to write to and unpack your DMS there. You'll then have a floppy image show up on  your WB.

A .run file is a self extracting LHA archive. Essentially the archive is packed with LHA, but the archive also contains an invisible unpacking routine (which makes it just that little bit bigger) Unpacking the archive is as easy as opeing a shell window and typing the name of the file.

CAUTION!!!! .run files can easily be hex edited to allow the unpacking routine to slap pieces all over yourSYS: (and any other) drive.
How about replacing someone's S:Startup-Sequence with "C:Delete SYS:#? ALL FORCE QUIET"

Not that I've ever done it, but I know people who've had it done to them.
