Reverse engineering the .fs format
Reverse engineering the .fs format

New MessageReverse engineering the .fs format (modified 0 times) Sean
For those of you interested, I've been reverse engineering the .fs file format. My findings are located at: http://www.azstarnet.com/~skasun/anat.txt

Hopefully, I'll finish REing it soon, and you'll be able to uncompress .fs files under linux.

New MessageAll done, Source available for UnFS (modified 0 times) Sean
visit http://www.azstarnet.com/~skasun/unfs.c for the source to unfs.

It has some minor bugs right now, like file permissions aren't done correctly, file ownership and date stamps are non existant, and special files such as softlinks and devices are not going to expand correctly. But other than that, you can expand a .fs and browse through the files.

Umm, maybe I'm missing something, but why don't you just mount them under QNX via the "vdir" command? There isn't anything terribly exciting in them anyway. That's where the browser, emailer, RealAudio player et al are, along with the OS images, which get mounted anyway... Are you simply trying to make this possible via Linux instead?

Yeah, you can just use vdir in qnx, but qnx sucks. I'd rather unzip the .fs files under linux so I can browse through them with biew or some other hex editor. (That, and i don't have an IO yet, so the only way for me to browse around is with someone elses sandisk image under linux :)

Is your utility able to access files on the QNX "demo disk" ? I believe it is compressed,
and QNX "vdir" doesn't seem to be able to mount the .dat file
