Filtering folders and files

[piet200]

How do I configure a filter that does this:

Include every sub-folder underneath X:\Folder1\
Include every sub-folder underneath X:\Folder2\
Include every sub-folder underneath X:\Folder3\

within this filter I want only the data of sub-folders:

\A\B\*
\C\D\*
\E\F\*


Something else, how do I use a variable for only one character ?
The asterisk is for multiple characters, but I want for example to select the folders where the first two characters don't matter, but the third number should be a 2.

Is the question mark an allowed character ?

Example: folder??2\folderx

This doesn't seem to work.

folder122\folderx
folder133\folderx
folder144\folderx
folder250\folderx
folder261\folderx
folder232\folderx
folder213\folderx
folder313\folderx
folder311\folderx
