CAB file(CABinet file) A file format from Microsoft used to hold compressed files on its distribution disks. The Windows Extract program is run at the DOS command line to decompress the files. For example, to view the content of the WIN98_02.CAB file in the \WIN98 directory on the E: drive, you would use the /d (display) switch as follows:
C:\>extract e:\win98\win98_02.cab /d
To copy and decompress EDIT.COM from that same CAB file into the current directory, you would type:
C:\ANYWHERE>extract e:\win98\win98_02.cab edit.com
