Remove folders recursively only if they're empty

Hi,

Is it possible to a folder which can contains other folders (etc.) but ni files in it.

In fact my problem is that "RMDir /r" removes recursively but even if there are files in it.
"RMDir" removes only if the folder is compeletely empty (even if it has empty folders).

What I would like is to remove recursively my folders if they doesn't contain any files

First use RMDir for the folders inside the folder and then remove the folder itself.

But how can I do that if I don't know the exact tree?

Then you will have to check wheather there are files inside. The search functions in the NSIS Archive might help you.

Thank you.
I will try to create a recurse file search
