Uhm, they are zip files which should be unzippable by Winzip, right? I do my uploads in that because I thought it was the most simple and most compatible format. Would it be okay if you got 7-zip (
http://www.7-zip.org/)? That's what I use. It's good freeware stuff that can handle any kind of archive file I've come across. It'd save me figuring out what different format to use and then re-uploading all those again. I have a pretty slow upload speed.
Yeah the only problem is that Windows Media Player won't play these kind of tracks and It doesn't seem to go to MP3 format at all just a paper thing
