instead of extracting the whole thing..why dont you use unadf.. it extracts files out of the adf..so if you run out of memory..maybe you can at least get the executable out of it?
btw, .adz files are .ADF files in gzip format...
if you want..email me the .ADZ file..I'll decompress it and send you back the exe or exe + whatever folder it needs.
When you're saying you're tryin to extract it.. do you have the compressed image in ram already, then trying to extract it also? cause 880k + 880k = 1.7 megs or so...(+- a few K since its compressed.)
