Apply password to several files

Volcano

Using Quicken Home and Business Canadian edition.

I have been using Quicken for several years without password protecting the files and their backups. Is there any way to batch protect all the files with a password wihout opening and applying a password to each one?

There's no such function in Q US, so I wouldn't think Q CAN has such.

How about just passwording the whole computer?
