action button on %L empty

[Hurdet]

I have a script:

for $i=0 to $CmdLine[0]
MsgBox(0,222,'"' & $CmdLine[$i] & '"')
Next

i have a button:
c:\Program Files\AutoIt3\AutoIt3.exe
k:\aaaa.au3 %T %L

It work if i select any but if i not and set cursor on root folder (not have %L) it not hit.
But i would to execute a action also if i not select.
Do it not possible?

This is not supported, sorry. TC cannot know what it should do when there are no files and you use a parameter which refers to files.
