Copy directory structure but not the files?

[quote="leo"]Since this gets asked every so often I've posted about it in the Buttons & Toolbars forum, with some screenshots to help people who aren't familiar with creating filters:

[Recreate Empty Directory Structure)[/quote]

ok, finally got a chance to work on this and got it running, sort of ....

let's say i have a complex deeply nested stucture 'bob' and under 'bob' is a large bowel of folders and so forth

now i make a folder 'joe' (parallel to 'bob' ) and want the same structure under 'joe' as 'bob'

if i go to the folder tree to push the structure of 'bob' into 'joe' it doesn't work (doesn't do anything)

if i go to the window which has the contents of 'bob' i have to select all the folders for it to work

if i go up a level then 'bob' gets put under 'joe' which is not what i want

i hope that was clear, maybe another way of posing the question is:
why doesn't this button work from the folder tree?
thanks for your help
