Where can I find the external programs required for ARC, ARJ, and LHA files?
WinZip® 11.2 and later no longer support external ARC, ARJ, and LHA programs however, integrated support for LHA has been added. WinZip 11.1 and earlier versions require external programs while working with ARC, ARJ, and LHA files. You can obtain the ARC, ARJ, and LHA programs from the following Internet sites (among others (this information is current as of April 2008)). Please note the upper/lower case format of some directory names — you may need to respect the case of directory names if you login to one of these sites. (Please keep in mind that these programs will not run under 64-bit Operating Systems) You can gain access to an ftp site by using a URL of ftp://sitename (e.g., ftp://ftp.simtel.net).
