don't know if this is an easy task, for one hour programming, or not, but this kind of application can be one of the most useful kinds that exists, still i didn't fount something done yet: a selective multiple file deleter. the idea came to me after using another application which renames multiple files based on user created rules. why not delete files in the same way? for example delete all the files having the extension *.etc in folder x, y and z. or all the files/folders containing numbers in their names.
