[Solved] Empty folders

[w64bit]

Create a folder named Folder 1
Inside it create Folder 2
Search for empty folders with empty: => Folder 2 is displayed
Delete Folder 2 => the list is not refreshed to display Folder 1, which, now is empty.

[void]

This is a limitation with empty:

All empty folders are calculated when you first perform the empty: search.
This information is not maintained in real-time for performance reasons.

I've added update empty: in real-time to my TODO list, if the performance hit is too much I'll add it as a ini option.
