All mp3's accidentally deleted

Ok I wanted to share the 3,000 mp3s I have collected over the years, but one I had them all shared I found out that people couldn't connect to me anyway because of the router in my apartment. So there was no use in leaving my music folder in the shared section of limewire so I went to remove it. I couldn't figure out how to remove the file from the list so I looked in one of the menus and saw "Delete Folder." I thought it meant it would delete it from my list of shared folders, but nooo...it deleted it from my hard drive. All 250+ full albums I had on my computer. So...what's the best recommendation for file recovery? Anyone have a preference in software? Please help. Thanks.
