Thanks, Luis, that works.
99% of the time I will want to search only through files in my project, not some directory; so in that "Find" box, I'll want the "File Types" and "Directory" fields to be blank. However, the Find box doesn't remember that I want them blank, so I have to clear both boxes every time I want to do a multiple file find.
Is there some way to make those two boxes default to blank? I know CVI strives to be keyboard-efficient, so I'm guessing there's some way for this.
