Use folder name as album name

I have my audiobooks stored like this:
D:\audiobooks\dan brown\da vinci CD01<filenames>
D:\audiobooks\dan brown\da vinci CD02<filenames>

My questions is if it's possible to read the folder name and use this as a tag for ALBUM ?

In this case I would then be able to tag my ALBUM tag with "da vinci CD01" for the files in that folder and "da vinci CD02" as the ALBUM tag for the files in that folder etc.

I know it's possible to read the folder_path, but I just want to retrieve the folder name of the folder where the files are stored - not the complete path.

Thanks to all - Jezper

It's possible by using the converter Filename - Tag where you can denote directories with the backslash \ character:
