Importing into the meta database

I’ve got an external drive that has a root directory where I keep subfolders of all my sound effects. I’m currently importing the entire root into AF. My question is, say I import the root again, does AF recognize that all the files already exist or does it duplicate those entries in the database? I ask mostly because I’m wondering what the best way is to organize and update my collection of libraries and the AF database. As I purchase more libraries, I’m wondering if I can just rescan the entire root or if I need to scan sub folders that I add individually.

Thanks.

It will duplicate them. Why? Because you can have the same sound in many places, so the original path is used as a way to distinguish it. You can use the relocate feature to move them in the Metadata Database Manager. Make a backup first!
