Delete with Filter for "Folders AND Size == 0"

I am trying to use the delete filter for the first time. I want to delete empty folders.

I select empty folders, enable filtered delete with "Set DELFILTER=Toggle", push Del, then I try the filter:

2017-08-10 00_40_55-File Filter - Directory Opus

But nothing is deleted.

Using the same filter for other operations works well. Please try to reproduce. I am using the latest version, 12.6.

Does it work for you if you use Shift + Del to bypass the recycle bin?

(Please try with some test folders first in case it deletes more than expected, with any delete/filter test.)

Yes, it works. Does this means there isn't a bug?

It may still be a bug, but I wanted to make sure we're seeing the same thing.

Need to investigate more to find out exactly where the problem is, but I think it should work with both even if it's only working with non-recycle bin at the moment.

Some news? I have the same problem… (DOpus 12.10.4)

But does the delete filter not work in folder tree?

Thanks
