Version History:

Superceeds IBM DOS 3.10. Provides full support for 720k floppy drives. Prerequisite for the IBM Token-Ring Network. Provides a new command (REPLACE) to replace all occurrences of file on a disk. Provides a new command (XCOPY) to allow copying of files from more than one subdirectory. Provides for label checking when formatting a fixed disk. (FORMAT) will not proceed until the volume label is entered correctly by the user. DOS 3.20 is an upward compatible enhancement to DOS 3.1 and contains maintenance updates. Requires 44k of memory to operate. Additional interrupt 21H function calls provide enhanced file management and support for the IBM PC Network environment.
