  19. Compression/Decompression  Utilities, a breif description of  Squeeze,
  20. Unark, Uncrunch, and Unsqueeze.
  21.  
  22.      "Squeezed" files are always signified by having the extension tail of:
  23.  
  24.                                      .?Q?
  25.  
  26.      The following are some examples of filenames of squeezed files
  27.  
  28.  
  29.                     PIP.CQM       =  Squeezed  PIP.COM
  30.                     PUT.CQM       =  Squeezed  PUT.COM
  31.                     HELLO.DQC     =  Squeezed  HELLO.DOC
  32.                     READ-ME.TQT   =  Squeezed  READ-ME.TXT
  33.  
  34.  
  35.      Here is what it would look like to use SQ.COM to "squeeze" PIP.COM:
  36.  
  37.                         (note the command line syntax)

  48.      And  that  is  all  there is too it! SQ.COM takes  pip.com  and  makes  a
  49. SQUEEZED file named pip.cqm which is smaller.
  50.  
  51.      We can also use normal wild card syntax and squeeze multiple files at the
  52. same time. Here is an example:

  68.      "Arkive" files are always signified by having the extension tail of:
  69.  
  70.                                      .ark
  71.  
  72.      The following are some examples of filenames of Arkived files:
  73.  
  74.                                    PIP.ARK
  75.                                   HELLO.ARK
  76.                                  READ-ME.ARK
  77.  
  78.      Here is a look at the syntax for the unarc.com utility:
  79.  
  80. A>unarc arkive filename
  81.    ^      ^       ^
  82.    1      2       3
  83.    |      |       |
  84.    |      |       This is the file which you want to extract from the arkive
  85.    |      |
  86.    |      This is the Arkive to which your file is to be extracted.
  87.    |
  88.    This is the command to call the unarc.com utility.
  89.  
  90.  
  91.      (2)  It  is  not necessary to put the .ark tail, just  the  name  of  the
  92. arkive.
  93.      (3)  Wildcard syntax can be used when specifying which files  to  extract
  94. from the arkive.
  95.  
  96.      With unarc.com it is necessary to specify the drive letter for where  the
  97. arkive is and where the files to be extracted are to go.
  98.  
  99.      Here is what it would look like to use unarc.com to extract PIP.COM  from
  100. an "Arkive" called pip.ark.
  101.
