File Sorting Utility Download
If you are clever you have probably already figured out what this program does, but for those who aren´t that clever I´ll explain anyway. FSU can copy/move files from several sources into for instance folders sorted by letter. FSU is specialized for sorting mp3-files, it has an option that can "fix filenames". If you only want to fix the filenames you choose the method rename. FSU has now many advanced features to clean up filenames and ID3 tags.
