Duplicate Music Files Finder Portable uses advanced search techniques to detect duplicates (it searches MP3s TAGS, detects duplicates even if the file names are not the same etc). If duplicates are found you can delete the files you want: just check them and press the right mouse button. You can also play the selected files in your favorite Media Player to see if they really are duplicates. Even though Duplicate Music Files Finder is specialized in detecting duplicates of music files, it does not mean that it can be used only for these file types. You can use the CRC Match or Exact File Name match methods to detect duplicates of other file types.
