If you need to retrieve a list of directories, then take a look at the DirPlus() or any other DIR() UDF and read DIR() Primer and File Operations in the FAQ Forum.

Then you can do this:
code:
$string='F:\CMD Files DOMAIN\USERNAME:F'
$dirloc=''F:\CMD Files'
$userperm=substr($string,len($dirloc)+2)
if instr($userperm,':')
  $userperm=split($userperm,':')
  $user=$userperm[0]
  if instr($user,'\')
    $user=split($user,'\')
    $domain=$user[0]
    $username=$user[1]
  else
    ; error handler
  endif
  $perm=$userperm[1]
else
  ; error handler
endif
or something like this.
