title: How can i extract compressed .cmpr file ? (application/x-compress)
body: <p>Been trying so hard, searched the entire internet, barely even found some reference to this kind of compression;</p>
  <p>I have a compressed file on ubuntu, with extention <strong>&quot;.cmpr&quot;</strong>,  i need to extract it, and nothing had
  worked for me so far, tried unzip, bunzip2 and gunzip, and tar -xv; and also tried everything with
  $(file -i archive.cmpr) - the file name is &quot;archive.cmpr, which gives <strong>&quot;application/x-compress&quot;</strong> as mime type.</p>
  <p>Can someone please help me found out how to extract this ? (without external software if possible)</p>
