Subject: The .arc .arj .lzh .pak .rar .uc2 .zip .zoo extensions

9. *****
 Q: I now have the files, but they have this .zip (or .arc, .arj,
.lzh, .pak, .rar, .sdn, .uc2, .zoo) extension and they won't run
then I write their name at my DOS prompt.

 A: The files are packed (also often called archived) entities.
These are special formats of compressing files and packing several
files together. This is usually standard knowledge for PC users, and
if you are not familiar with the system, just ask a knowledgeable
fellow user. What you need is the proper unpacking programs such as
PKUNZIP, UNZIP, ARJ, ARC, PKXARC, PKUNPAK, PAK, LHARC, LHA, UC2,
RAR, ZOO and so on. And, you will find all the necessary tools for
handling packed files in the /pc/arcers directory. For example, if
the extension is .zip get the self-extracting

 pkz204g.exe PKWARE's pkzip, pkunzip, pkzipfix, zip2exe for .zip
or

 unz540x3.exe Info-ZIP's self-extracting unzipper (with 386 version)
For the Windows 3.1x environment use e.g.
 629038 Sep 26 1997 ftp://garbo.uwasa.fi/windows/arcers/wz16v63.exe
 wz16v63.exe WinZip for Win 3.1 w/Built-in ZIP, TAR, gzip, compress
   Note that if you use an out of date PKUNZIP version, it may
report a CRC error in your .zip file although the true reason for
your problems is using the out of date version. Likewise, if you
have failed to transfer the file in the binary mode, you may get an
unexpected, illogical error message like "requires PKUNZIP 3.0 or
higher version".
