Communication Archiver "Comarch"

What is Comarch?
Comarch is short for Communication Archiver. Maybe most of you are not
familiar with the term "Communication Archiver". It can be briefly
explained as an archiver designed for the use on communication (electric
traffic and distribution). This is to explain how Comarch is different
from those well-known archivers such as ZIP and LHA.


Comarch has the following advantages:
1) The resultant archived file itself is encrypted, so that no other people
 than the user can decode it.
2) Directory structure can be stored into the archive.
3) Without decoding the archive, the contents can be directly executed as the
 archive is regarded as a drive (folder).
4) With its security function, many new applications can be considered

=================================================================
Some Tips on Comarch Usage:

*It's safe to exchange confidential mails/letters through internet or public
 domain BBS's.
*The hierarchical structure for individual users on a large scale server can
 be simplified, and yet even the system administrator cannot access to the 
 information contained in the archive made by other than him.
*Pay data such as video and PC software can be stored as an archive on a
 network or CD-ROM, so that the seller can lease such to the customer on an
 hour or time basis. 
*Even non-executable files can be controlled by the password. It can simplify 
 the distribution of demonstration files or files containing secret individual
 information to be exchanged on the purchase of, for example, software or any
 other commodity.
*Even those who are not capable of programming or do not have a server, can 
 open an e-shop.
*There are many other possible applications considered depending on your idea.
