i played some video files on wmp and later deleted them from my shared folder. however, when i open wmp, the files are still there, but i cannot play them (i get a "Windows Media Player encountered a problem while playing the file. For additional assistance, click Web Help." message). but when i try to right click and delete, or right click and Open file location, nothing happens. anyone know how to delete these files for good? (im using wmp 11)
