Previously I have downloaded hundreds of .mp3 files, played them in Winamp, then used mp3Direct Cut to get rid of silences at the beginning and end of the files. I then saved the edited files, adding the figure 1 to the song title to distinguish it from the original, then played them again with Winamp to check they were ok, and finally deleted the original files, deleted the figure 1 from the title of the edited files, and then cut and pasted them to the folders I wanted them in. Now when I try to play the edited files I can't unless I first take ownership of them. I have never had this problem before, and if someone can give me a solution I would be very grateful.
