A way to apply whitespace settings to everything in a folder

Hi all,

I recently discovered that you could have whitespace cleared on save. However all of the scripts I've been working on haven't been using this. So now every change I make results in hundreds of changes to the file, because whitespace has been removed.

Is there a way to target a directory and have all scripts below the directory (including subdirectories) apply the new whitespace setting?

Thanks!
