are you meaning changing the file names? You could try using a batch file renaming program in combination with regular expressions to achieve what your doing. You say I don't make sense? You could set the program to replace the "-" with a "(", then append a " )" to the end of the file name. For example, what I just said would be like this Before: Mattus - song1 - ysm remix.mp3 After: Mattus - song1 ( ysm remix ).mp3 Can't think of any batch file renamers for windows off the top of my head unfortunately, shouldn't be hard to have a google and find one though. As an example for a program, here is one I have used for mac in the past: http://www.publicspace.net/ABetterFinderRename/
