Search for and clean files with certian extentions.

Hello there, I have been using CCleaner for a long time now and just now decided to see whats happening in the community.

I also have a question: Is there any way to have CCleaner search for files with an extension, or with a part of a word in the file name and delete them?

Like I want to search my whole harddrive and delete all the .mdmp files, or log1*.log files.
