To be worth even a reasonable shareware price, an
OS/2 compression utility has to offer some advantages over the
freeware Info-Zip. Compared to Info-Zip, RAR produces somewhat
better compression rates in somewhat worse time. Take a look at
the below table for a compression and time comparison. On
features, RAR has several advantages over Zip. RAR provides a
built-in text-mode interface which allows point-and-clip
navigation of archives (even non-RAR archives, such as ZIP, UC2,
LZH; some functions require the presence of these utilities,
however). From this interface, it is simple to view compressed
files, selectively add, delete and extract files, change
extraction path, and so on. Disk- spanning of archives is much
better implemented in RAR than in Zip. Unlike in Info-Zip,
individual files of large size do not prevent the creation of
multi-disk archives which include them. Self-extracting archives
can be created; and if DOS-based SFX's serve your needs, there is
even a scripting language for creating an installation front end
within SFX's (allowing recipient to view product information,
choose installation options, etc.). The OS/2 SFX stub, while much
smaller than the Info-Zip SFX stub, does not provide such
installation scripts currently. The OS/2 version of RAR also does
everything an OS/2 user should need in handling long-filenames,
extended attributes, recursed directories, and hidden/system
files.
