Uncompressing archived files

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 or CLI (Command Line Interface) prompt.

Most of the files at Garbo 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. But 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, which is the most common option at Garbo archives, get the self-extracting

  ftp://garbo.uwasa.fi/pc/arcers/pk250dos.exe
  PKWARE zip un/archiver, with long filename support
or
  ftp://garbo.uwasa.fi/pc/arcers/unz552x3.exe
  unz552x3.exe Info-ZIP's self-extracting unzipper including 32-bit

Note that if you use an out-of-date PKUNZIP version, it may report a CRC error in your .zip file although the true reason for your problems is using the out-of-date version.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".

For the (now totally obsolete) Windows 3.1x environment use the facilities from the /windows/arcers/ directory, e.g.
  ftp://garbo.uwasa.fi/windows/arcers/wz16v63.exe
  WinZip for Win 3.1 w/Built-in ZIP, TAR, gzip, compress

For the Windows Win9x/NT/2K/XP/2K3 etc. (i.e. the 32-bit) environment use the facilities from Garbo's /win95/arcers/ directory or from external sources such as the commercial WinZip or the freeware ZipCentral.

For the UNIX environment connect to Garbo's /unix/arcers/ directory or visit the external Info-ZIP site.

What is tar.Z? Where can I find tar for MS-DOS? What about uudecode, compress?

A: These formats (tar and Z) are (usually) UNIX files. The files with the .Z extension are compressed files which you'll need to uncompress. Uncompress is available as a standard feature on UNIX systems (try "man uncompress"). You can get it for MS-DOS as well e.g. as comp430d.zip. You can also use gzip124.zip (both for .Z and .gz files).

Tarred files with the extension of .tar ("tape archives") can be handled with a tar program on a UNIX system, or on MS-DOS with the utilities like tar4dos.zip or tar320g.zip. On UNIX try "man tar". Also see

  ftp://garbo.uwasa.fi/unix/ts/tarzfaq.txt
  What are and how to handle tar.Z and tar.gz files

A2: Uuencoding is a 7-bit format for sending files in ordinary ascii format. On a UNIX system see "man uudecode" and for MS-DOS get uuexe656.zip.
