There are three main scans that FULL-DISKfighter for Mac (Beta) undertakes: Junk Scan – that looks for un-needed systems files, potentially un-needed language files and potentially un-needed program components; Duplicate Scan – that scans for duplicate files on your computer; and Files Finder – which scans for files over a certain size, defined by you. Once scans have completed, you can click on the icon for each scan to be presented with the results of the scan, which then allows you to select which files that you wish to delete.
