Ilikefree, I have no idea what you mean.
Lorien, the site is Stonesthrow.com. I can't give you a link to the actual page because its a download manager on the website. I purchased to music and then it sits in the DL manager until I grab it. I don't know how they were compressed. I've been told they are encrypted because when I have gotten music in the past, after I unzip the file the text for the document is green. When I try to move the file around it says I don't have permission. I did some research on that and was told they were encrypted, that's why the text is green instead of black. It sounded like a simple fix though, apparently properties - adv. options- blah blah.
When I open the folder and click on a song, this is the info it gives me. Type - MP3 format sound. For a random song the compressed size is 7529 kb. The actual size is 8122 kb. The ratio is 8%, whatever that means. Also is I right click a song, under the method tab, is says deflated.
When I get home tonight I will try gabbing a 7-zip. Thanks for the replies all!
