What am I doing wrong (compressed file)

Ok, I use winace to archive my files. And I have a 10gb .ace file that I created prior to me formatting my primary drive. No problem. But now, come time for me to want a mere 6mb file extracted from the archive it takes 2hrs 35min to extract the freaking FILE!!!! Hmm. 2.5 hours. Sounds a lot like the amount of time it took to make the original 10gb file!! I MUST be doing something wrong! I have noticed that during the whole decompression process it spends MOST of its time analysing files. Don't analyse damnit!! Just pluck the freaking 6mb file and put it on my desktop. Help, guys. Please. thank you

Exactly what is a .ace file? Never heard of it and what program are you opening it with?
