This is a nice example for LINQ, but *don't* actually use it to search for files!!! This is not DLinq, which is transformed into SQL - this actually retrieves an array of _all_ the files in a directory, with all their attributes, and then performs a search in the returned array. This is *a lot* slower if the directory contains lots of files!
