file extension

[Gif]

is there any way to get the extension of a file?

like to know if it is .exe or .zip or even if there is not any extension (directory)

#include <File.au3>

_PathSplit()

...or even if there is not any extension (directory)

Not having an extension is NOT a good test for a directory!

not having an extension means its a directory , however the "problem" is solved

I think what PsaltyDS means is that a directory CAN have an extension. For instance, I have several directories on my drive that have been renamed to something with a descriptive extension: like if I want to compare a fresh program installation to an corrupted one, I'll rename the original from something like

C:\Program Files\myProgram

to

C:\Program Files\myProgram.old

and thus my directory now has an extension. So any code that differentiated between files and directories merely on the basis of whether there was an extension or not would think "myProgram.old" was a file but it's not.

My point exactly, AND that a file might not have extension, yet not become a directory. Run this:

$TopDir = @TempDir & "\Extension Demo"
Dim $avDirs[2] = ["\DirNoExt", "\DirWithExt.txt"]
Dim $avFiles[2] = ["\FileNoExt", "\FileWithExt.txt"]
For $d = 0 To 1
    DirCreate($TopDir & $avDirs[$d])
    For $f = 0 To 1
        FileWriteLine($TopDir & $avDirs[$d] & $avFiles[$f], @HOUR & ":" & @MIN & ":" & @SEC)
    Next
Next
ShellExecute('explorer', '"' & $TopDir & '"')
