  3. .SYNOPSIS  
  4. Search for (filename) strings inside compressed ZIP or RAR files (V2.8). 
  5. .DESCRIPTION 
  6. In any directory containing a large number of ZIP/RAR compressed Web Page files  
  7. this procedure will search each individual file name for simple text strings,  
  8. listing both the source RAR/ZIP file and the individual file name containing 
  9. the string. The relevant RAR/ZIP can then be subsequently opened in the usual 
  10. way. 
  11. Using the '-Table' (or alias '-GridView') switch will show the results with the  
  12. Out-GridView display. 
  13. .EXAMPLE 
  14. extract -find 'library' -path d:\scripts 
  15.

  43. Note that there may be the odd occasion where a 'non-readable' character in the 
  44. returned string slips through the net!
