Get Filepath And Filename From String

[magOO]

Hello!

I get a Filename from the commandline to my Script

How can I get now the Path, the Filename and the Fileextension from the String

Example:
$filename = $CmdLine[1]

When $filename is C:\Program Files\Directory\Filename.exe then i want to get these Strings:

$Path = C:\Program Files\Directory\

$Filename = Filename.exe

$Filetitle = Filename

I hope somebody can help!

Thanks for your Help!

Just check how many \ are in the string, look for the last one and trim everything on its left and you have the file name.

Check how many . there are in the filename, look for the last one and trim everything on its left and you have the extension.

If the file has no extension and there are dot in the filename you can have problem...

lastly check the filename lenght and trim this lenght from the full filename right to have the path.

This is a script that can filter out the field you want:

$TEST='C:\Program Files\Directory\Filename.exe'
$FILENAME=""
$PATH=""
$TITLE=""
$EXT_START=0
$FILE_START=0
For $X = StringLen($TEST) To 2 Step -1
   If StringMid($TEST,$X,1) = "." And $EXT_START = 0 Then $EXT_START = $X
   If StringMid($TEST,$X,1) = "\" And $FILE_START = 0 Then $FILE_START = $X
   If $FILE_START > 0 Then
      $FILENAME = StringTrimLeft($TEST,$FILE_START)
      $TITLE = StringLeft($FILENAME, $EXT_START - $FILE_START -1)
      $PATH = StringLeft($TEST,$FILE_START)
      ExitLoop
   EndIf
Next
MsgBox(0,'test',"filename:" & $FILENAME & @CR & "Title:" & $TITLE & @CR & "Path:" & $PATH)

Use this function (Watch wordwrap).

Many Thanks!

I'm very new to this, but couldn't you just use StringSplit() to split the path by "\". Then use a UBound -1 to get the last part of the array, the filename w/ exe. Then trim off the last 4 chars to s to the filename wo/ the exe.

Guess where Micro$oft got the idea from in the first place.

Unix (remove a lot of stuff) -> CPM (add a little bit) -> DOS (add a GUI) -> Windows

But it is still missing the good stuff, including security and 700 utilities.

Windows does seem to accept the / in windows explorer, but the command prompt only lets / be an option marker.

On XP Pro SP-1, I can use \ or / interchangeably (Or mixed for that matter) in both explorer and the command line. Some applications may have a problem with *nix style, though because they are looking for a /<switch> notation. But that's an application incompatibility and not really a Windows/MS-DOS one.

Since Unix-style paths could be used, you should StringSplit by "/\"

Stripping off the last four characters works if all parameters will be EXE files but will cause problems it HTML of JPEG could be paramters.

Interesting point.

Extensions are not always 4 characters (.xxx). How about:

Func GetFile($FilePath)
    Local $x, $f, $i

    $x = StringSplit($filepath, "/")
    if $x[0]=1 Then
        $f=$FilePath
    Else
        $f = $x[$x[0]]
    Endif
    $x = StripSplit($f, ".")
    $f = $x[1]
    For $i = 2 to $x[0]
        $f = $f & "." & $x[$i]
    Next
    Return $f
EndFunc

            This is nice but I would recommend changing the code that breaks out the file extension to search from the left rather than the right since files can have multiple extensions to them (ie., testimage.jpg.bak)Change: ; Check the filename for an extension and set it
    For $i = StringLen($fname) To 0 Step -1

To:

; Check the filename for an extension and set it
   For $i = 0 To StringLen($fname)

I don't know if Autoit is smart enough to only evaluate StringLen once or if that is done on each trip through the loop, will have to test that one day.

even M$ admits that "/" works.

From: UNIX Application Migration Guide

"In most cases, Windows can also handle the forward slash (/) as a path separator. However, when building cross-platform paths, scripting language compilers can misinterpret even correctly used file path separators or methods."

Thats one of the two reasons getting the extension is done from the right (The other is a small performance gain). The extension of the file name you use as an example is ".bak". If performed from the left, the extension would be ".jpg.bak" which is not correct. If you are basing your logic on the assumption that anything after the first period is the file extension, then take a look at a file with the name, "Photo.Of.Me.On.My.Vacation.jpg". Using the flawed logic of starting from the left, the extension would end up being ".Of.Me.On.My.Vacation.jpg". Quite obviously, that is not correct. The way the function is written now is the correct way.
