FULL-DISKfighter (US$9.99) from SpamFighter is a new disk utility meant to slim down your Mac’s hard drive. How it goes about this is by scanning your Mac for files it considers unnecessary or redundant. It’s broken down into three sections.
The first one is Fast Clean Up which searches for junk files such as files left over from deleting programs, language files that you won’t use and Universal binaries that add Power-PC compatible code that will never be used since they are not used by your processor.
The second function is Duplicates Finder which according to SpamFighter, include files that are the same but given different names. You can view them and delete them to save space.
The third function is File Finder that searches for files that are either large or haven’t been used for some time. This can be quite helpful for finding large video files or other space hogs that you’ve forgotten about.
