Preserve filenames from files with no metadata? (using fromfilename)

how do you import files (with no metadata) with original file/directory name and structure?

==========================

im trying to import a bunch of files like

> folder1
>    folder2
>        pk000000_00_0A (5).flac
>        pk000000_00_0A (8).flac
>        pk000000_00_0B (5).flac
>        pk000000_00_0B (9).flac

but running ‘beet import ~\directory’ gives

folder:

> [] 
>    [_]
>       01.flac
>       02.flac
>       03.flac
>       04.flac

beet list

>   - -
>   - -
>   - -
>   - -

config:

plugins: inline fromfilename
import:
copy: no
write: yes
move: yes
autotag: no
duplicate_action: ask
detail: yes

If you don’t want to change the filenames for your music, you can disable the import.move and import.copy configuration options, as described at the beginning of the “Getting Started” guide.
