Working with archives (ZIP, ARJ, LZH, RAR, UC2, CAB, ACE)

From windows Commande Help

Important note:

Most packers do NOT support Win95/98 and WinNT long filenames! Exceptions are the internal ZIP packer built into Windows Commander, Zip-NT (ftp://ftp.uu.net/pub/archiving/zip/) and very new versions of UC2, RAR, LHA and ACE. If possible always use the internal ZIP packer! In this version Windows Commander checks the created archive directly after packing to ensure that it isn't defective. This can be disabled by adding the line VerifyZip=0 to the section [Packer] in wincmd.ini.

What are archives?

Archives (packed files) are normal files with the extensions .ZIP, .ARJ, .LZH, .RAR, .UC2, .CAB, .ACE. Such files contain other files in a compressed form, which takes up less disk space than uncompressed files. To access these files, they have first to be uncompressed. Files with extension .TAR come from the UNIX world - they are usually packed into a GZIP file (ending with .GZ). They cannot be modified with Windows Commander. The CAB archive format is used by Microsoft for installation programs. CAB archives can only be unpacked by Windows Commander. CAB files are only supported by the 32 bit version.
