The .CAB file extension is used for Windows cabinet files, which are archive format files that store data that has been compressed. Compressed files take up less space on the computer's hard drive where they are stored. If the hard drive is damaged, the files stored there, including CAB files, can be corrupted. You cannot view corrupted CAB files. There are free programs available for download that can repair corrupted CAB and other files.
