                  ;  -all attributes of file combined with "|" to output
                  ;
                  ; "READONLY|HIDDEN|SYSTEM|DIRECTORY|ARCHIVE|
                  ; DEVICE|NORMAL|TEMPORARY|SPARSE_FILE|REPARSE_POINT|
                  ; COMPRESSED|OFFLINE|NOT_CONTENT_INDEXED|ENCRYPTED"
                  ;  -file must have specified attributes
                  ;
$var              ; Result:
                  ;    $var=attr1|attr2|... (if used "ALL")
                  ;    $var=1   file has specified attributes
