Getting the grips of adding, reading, deleting etc. files pretty well.
As of R11, I'd like to add my licenses in the UserPrefs as suggested, in a folder.
But, if there are now license files in this folder, I'd like to
delete it as well.

So what I can't figure out is how to check for an empty directory
(Folder with no files in it on the disc).
I can brows to this folder but then since I have no name to add
to the path I'm stuck.

Any pointers of how to do that?

Cheers
Lennart

Use the BrowseFiles class.

Hi Robert. Yup that is what I'm trying.....
But I can't get a TRU or FALSE out of it as it seems..

Thing is this only prints the "Name is" part, the rest (var name)
simply doesn't print anything, its blank(!?).

So, I'm still a bit lost I'm afraid..
There is the GetNext() option, but not "GetDown()" or GetIn() to
"get into" the folder to check.

There is an example at the bottom of the BrowseFiles documentation:

var bf   = new(BrowseFiles);
var path = GeStartupPath();

bf->Init(path,FALSE);

while (bf->GetNext())
{
    if (bf->IsDir())
      println("dir ",bf->GetName());
    else
      println("file ",bf->GetName());
}

bf->GetNext() gets the first then next files/folders under the folder set in bf->Init().

Ah, I used that example to start with and also got that "blank" print.
Just tried this:

And even if MyFolder was empty, it wasn't!
There is a frigging hidden ".DS_Store" file there!

So the BrowseFiles seems to work but what to do with hidden files?
I'm on Mac, is there anything similar happening in Windows?

On that in COFFEE, I don't know. You may need to check for that particular file by name when you get a hit, ignore it and continue on.

Thanks Robert.
It looks as if I'm on the wrong track anyway....
Recreating the "MyFolder" (From Finder) so there is nothing in it,
even no .DS_Store file, I still get a "Something here!" using the code
above.

Maybe someone from Maxon have a tip after the weekend.

Cheers and thanks

I can not confirm this. If I create an empty folder on OSX with Finder->New Folder it is empty for Cinema as well. My code:

Thanks Matthias. I got it working (and have learnt a lot about file handling the last couple of days because of making license files:) )
Sorry to not tell.
