These space-hogging duplicate files can build up over time and litter your hard drive, especially if you use your computer to regularly download or rip music CDs. You can reduce this clutter and free up hard drive space by simply using a free duplicate file finding software tool. Using Duplicate Cleaner Free for Audio Files As well as using this special software for streamlining your music library, you can remove multiple copies of photos, videos, and other types of files. In this tutorial, we're going to use the free version of Duplicate Cleaner (Windows), which has a special mode just for audio files. If you use a different operating system, such as macOS or Linux, then try Duplicate Files Searcher. Follow these steps to use the program and clear those duplicate files. Switch Duplicate Cleaner to audio mode. This specifically searches the metadata in audio files to try and find duplicate songs or pieces of music. To switch to this mode, select the Audio Mode tab via the main Search Criteria menu screen. If you want to filter out specific audio formats, then you can use the exclude search function. For example, type *.flac to filter out any files in this format. Before you start to scan for duplicates you need to tell the program where to look. Select Scan Location from the menu near the top of the screen. Use the folder list in the left pane to navigate to where your song library is stored. Highlight a folder (or entire disk volume) that you want to add and then select the Arrow icon (white right-arrow). You can also double-click folders to select sub-folders if necessary. If you have music stored in more than one location then simply add more folders in the same way. Select Scan Now to begin searching for duplicates. When the process has finished, a statistics screen will be displayed giving you a detailed report on the duplicates that have been found. Select Close to proceed. If the duplicate list is large then select Selection Assistant (image of a magic wand). Hover your mouse pointer over the Mark sub-menu and then choose an option. There are a number of options that you can use to select files. Examples include file size, modified date/time, auto tags, etc. If for instance, you want to select the oldest files in the modified date/time section, then make sure you select the Oldest Files in Each Group option. Once you have marked the duplicates you want to remove, select File Removal near the top of the screen. There are a number of options available to remove duplicate files. If you want to send the files to the Windows recycle bin rather than deleting them directly, then make sure the Delete to Recycle Bin option is enabled. To also remove folders that don't have anything inside them, ensure the Remove Empty Folders option is checked. When you are happy with the way the duplicates will be removed, select Delete Files.
