hi thier if you are using limewire check were you installed it ie documents find the folder limewire and check in saved or shared or incomplete if its an incomplete file it will have a lletter followed by numbers ie t7685467 highlight this then press delete when the dialog box appears move it to the recycle bin if this does not work you will have to download removal software thier is a trial program for 1month called ashampoo winoptimizer 5 download this program and go into privacy it has 3 sections file or folder or recyclebin wiper this should do the job if not well im sorry for wasting your time let me know how you get on

I tried deleting from the library and it still says it is being used by another and won't delete.

hi there if u cant delete the file because it is in use by another program go to incomplete in limewire and see if it is still downloding also see if u have tried to preview the file all previews start with a letter then numbers delete the preview then delete the file when the dialoge box appears press the move to recycle bin it should delete dont use the delete function in limewire which says delete from library and computer. its better to move it to the recyle bin then empty your bin or wipe it with a file wiper program there are some good ones available from cnet .com hope this was helpful let me know if u solved your problem
