sfap0 files - huge - what are they? -Sound Forge - PC

Subject:sfap0 files - huge - what are they? Posted by: fultro Date:6/14/2005 8:57:38 AM Vegas generates sfap1 for Video files that are ~3% of the file size of the original.. Whatever they are I do not have a problem with that .. However, and I think this is a fairly new experience, opening audio files in Sound Forge 6 generates sfap0 files that are at least 10 times the size of that file. I don't remember having that file in earlier versions of SF . Opening a CD size file in SF and generating a 5-6 Gig file that takes 6 or 7 minutes is a problem. And trying to cancel the generation in the progress bar at the bottom of the window just stops opening the original file ..Checking this out at another studio I work at that uses SF 8 and found that SF 8 didn't generate that file at all. Allright so upgrade to SF8 you say? Well not til it gets fixed - it is a big disappointment to this SF user since V4 . somehow a perfectly good app has been wrecked- at least from my experience from two differnet installations of it that I have tried and from reading this forum - and those particular installations have been updated to 8.0a . Also, I would still like to know what those files do and why I didn't get them before (though I could be wrong about that as it has been a while since I have had to use SF - especially with big files....).
