Import pdf

A long term but occasional Scrivener user, I am considering using S as a reference manager for my specialist law library. (I’ve considered Bookends, Sente and other dedicated reference managers but they are too scientific-research oriented for my needs.)

This question may have been asked/answered before but I’d appreciate please knowing approximately the maximum number of pdfs that could be imported into S, either the original or a link to each pdf in a different folder. I have approximately 200,000 pdfs to process, with about 10-20 new ones arriving daily.

Thank you
