Parameters:
  /file=<fn>             filename mask (supports multiple expressions separated by ;)
                         ( you can also use exclusions e.g. *.txt;-term1 )
  /file_regex=<fn>       regex'ed filename mask
  /path=<path>           path mask (supports multiple expressions separated by ;)
                         ( you can also use exclusions e.g. c:\temp;-term1 )
  /s                     search in subdirectories (DEFAULT)
  /ns                    do not search in subdirectories
  /da=<yyyy-mm-dd>       file date is after <date> (date format: yyyy-mm-dd)
  /db=<yyyy-mm-dd>       file date is before <date> (date format: yyyy-mm-dd)
  /dt=<c|m>              date type, dt=m (modification date) dt=c (creation date)
  /min_size=<size>       minimum file size (K/M/G modifiers supported)
  /max_size=<size>       maximum file size (K/M/G modifiers supported)
                         (size can contain one of the K/M/G modifiers,
                         e.g. /size_min=10M means size must be at least 10MB)
  /contents=<term>       find files containing the specified text
  /contents_regex=<term> regex'ed file contents search term
  /output=<fn>           write results to file <fn>
                         (if you also search file contents a 2nd file with content
                         results will also be created)
  /search                automatically start a search (useful if a .scanfs file
                         was used to load the search parameters)
  /exit                  exit when search is done
  note: the "/" before the parameters is optional
  for regular expressions
    1. instead of /file use /file_regex
    2. instead of /contents use /contents_regex
Examples:
1.  scanfs.exe path=c:\temp file=*.avi size_min=10m size_max=12m
2.  scanfs.exe /file=*.txt /path=c:\temp /s
     /da=2007-1-1 /db=2008-1-1 /dt=c /size_min=20m /size_max=30m /contents=123
     /output=c:\results.txt /exit
