FileExists-Method

3 posts in this topic

In AutoIt I can ask if a file exists.

How can I do this in AutoItX3? (... without using WinShell!)

You could use FileGetAttributes:

Func _FileExists($fileName)
    Local $Ret = DllCall("Kernel32.dll","int","GetFileAttributesW","wstr","\\?\" & $fileName)
    Return $Ret[0]<>-1; GetFileAttributesW return -1 if an error occurs
EndFunc
MsgBox(0, '', _FileExists(@AutoItExe))
MsgBox(0, '', _FileExists("D:\File\Not\Exists___rew"))

Thanks!

It works fine with:

Set fso = CreateObject("Scripting.FileSystemObject")
  fso.FileExists(YourFileName)

But I'ld like to get rid of all those Kernel and SystemObjects stuff.

And I wonder why it works in AutoIt, but not AutoItX3.
