Searh by regexp in a folder

[user8246]

I want to search through files/subfolders in a specified folder based on some regexp-pattern.
How can I do it?
This way doesn't work:
"C:\Windows\" .*\d\d

Try:
"C:\Windows\" regex:.*\d\d

[void]

Please make sure regex is disabled under the Search menu with the above search.
