Why no double underscores in file names?

[robsch]

I have found that cleanString() removes multiple underscores. Is there a special reason for this? Can I just drop this line (and in PHP the corresponding line in filemanager.class.php) if I want to allow muliple underscores? Or does that cause any problems?

It should not cause any trouble. You're free to remove pattern in cleanstrint() methods - both php and js files

Thanks!

Of course I know already the RichFilemanager. Will switch to it asap.
