Star ARC

This program was designed to extract Commodore ARC archives into disk images. It cannot create archives out of disk images and it cannot handle the completely different PKARC format. Star ARC is an external utility of The Star Commander but is also distributed separately.

CREDIT: Some algorithms and procedures of this program have been taken from AX (© by Chris Smeets, 1989).

1. Usage

STARARC [-]L <arcname>
STARARC [-]X <arcname> [-|/4|7|8|C|D|X[D|P|S]|Y] [<diskname>]



Type the path and the name of the disk images here (the extension is always ".d64" for 1541, ".d71" for 1571 and ".d81" for 1581 disk images). Leave this parameter blank to extract the archives into disk images with the same name. You can use long filenames.


Type the path, the name and the extension of the archives here (the default extension of ARC archives is ".arc"). You can use wildcards to list or extract multiple archives and you can use long filenames, too.


When decompressing an ARC archive, the program checks if the first file in the archive has the name "title". If it does then this file contains a comment which is displayed before decompression. However, the display routine can only handle the control codes $0D (carriage return), $0E and $8E (changing to lowercase/uppercase and uppercase/graphics character set). All other control codes are omitted.
