Although highly compatible both with PKWARE&#039;s PKZIP and PKUNZIP utilities for MS-DOS and with Info-ZIP&#039;s own Zip program, our primary objectives have been portability and non-MSDOS functionality.<br /> UnZip will list, test, or extract files from a .zip archive, commonly found on MS-DOS systems. The default behavior (with no options) is to extract into the current directory (and subdirectories below it) all files from the specified zipfile. A companion program, Zip, creates .zip archives; both programs are compatible with archives created by PKZIP and PKUNZIP for MS-DOS, but in many cases the program options or default behaviors differ.";
