Remove all non-numeric characters from multiple folder names

Hello, is there a simple way to rename all selected folders to remove anything non-numeric?

So deleting letters, underscores, spaces, and similar?

Thanks!

Answering my own question: use \D (has to be capital) in a regex find and replace

[lxp]

Try

Parameters for the Advanced Renamer
Mode:	Regular Expressions + Find And Replace
Old name:	[^\d]#
New name:	leave empty

[lxp]

\D

Even better!
