Music files, especially in large quantities, can take up considerable space on your computer's hard drive. Compressed music files, such as MP3s, take up approximately one megabyte per minute of audio -- depending on the quality. Uncompressed files, such as WAVs or AIFs, can take up much more space. If you want to remove music files from your computer, first you need to know how to access them. Next, you need to learn how to permanently delete them.
Locate the music on your computer. Proceed to the appropriate folder if you know where your music resides. Access your "Music" or "My Music" folder if you don't know where to find your music files.
Open the "Macintosh HD" folder, followed by your "Home" folder (your unique user name for your Mac) and your "Music" folder if you use Mac OS X. Open your username folder followed by "My Music" in Windows 7. Open "Documents and Settings," followed by your username folder, then "My Documents" and finally "My Music" in XP or 2000.
Highlight the song files you want to remove. Drag your mouse over a series of files or hold down the "Shift" key and click each song file individually. Click on any of the highlighted files and drag them all to "Trash" or "Recycle Bin" on your desktop.
Empty your "Trash" or "Recycle Bin." Select "Finder > Empty Trash" on your menu bar in Mac OS X. If using Windows, right-click your Recycle Bin and select "Empty Recycle Bin," or open the Recycle Bin and click the "Empty Recycle Bin" button.
If you would like to free up space on your PC while still saving your music, you can transfer it to a CD using a program like iTunes, MediaMonkey or Windows Media Player (all of which are free to download). Just load the music into your chosen media player, insert a blank CD-R into your CD-R or RW drive and click "Burn." If your player supports play lists (music folders), you will need to create a play list for each CD you want to burn. Audio CDs hold 80 minutes of music.
It is very important that you find and remove the original song files. Simply deleting a song from your iTunes or Windows Media library will not necessary remove the file from your PC.
