Filtering folders and directory|file lists

[Sovka]

I've got some problems and ideas with reflector
Problem^ I'm trying to backup windows user profile and filterout AppData\Local and AppData\LocalLow
i tried this:
mask *\AppData\Local*\*
regexp .*\\AppData\\Local.*\\.*
regexp .*\\AppData\\Local\\.* and .*\\AppData\\LocalLow\\.* separately
added "Ignore empty directpries" on, but programm still creating all directory structure in Local and LocalLow!
How can i filterout Local and LocalLow in user profile copy task?

Idea:
Is there any methods to show files and folders to copy before task starts?
I'ts easy to debug filters before task starting with this function.

The folders are being created but are empty. Check Ignore empty directories in the advance tab.

Ignore empty directories in the advance tab doesn't work for me.
Is there any way to not create filtered folders?
My work example is in bottom.
2/3 folders are filtered out, 5/6 files filterred out. Files doesn't copy, but folders are

The "Ignore empty directories" should delete the folders after they have been created.

My challenge with filtering directories is that
- first all directories will be created and
- afterwards (!) will be deleted (if empty)

I have some database directories with a lot of subdirectories (each database with more than 2500 subdirectories) and all of them will be created (and deleted afterwards) This takes 95% of backup time.

Example:

somewhere\ab.database\0\000
somewhere\ab.database\0\001
somewhere\ab.database\0\ and so on
somewhere\ab.database\1\001
somewhere\ab.database\1\002
somewhere\ab.database\1\ and so on
... and so on
somewhere\ab.database\F\ and so on


somewhere-else\xy.database\0\000
somewhere-else\xy.database\0\001
...
somewhere-else\xy.database\F\...

I completely want to filter out all "*.database" directories (and subdirectories) and do not want backup any files there.

Yes, that is unfortunately the case.
