How to Anlyze tracks in 'Files' not in Collection?

Hi Guys
total Newbie here so thank you in advance for any help.
I much prefer to use my music collection from the Files tab, fully organised in folders from external Hard drive.
Is there any way I can Analyze them while in the Files Tab without putting them into Collection tab? The 'Analyze button is permanently turned off within the Files Tab??
Also everytime I open Mixvibes it Analyzes each folder when opened?
Is there a way to stop this happening?
many Thanks
Goochie.
