Calibre as Note Manager

[Pierosparviero]

Does anyone know, if it is feasable to manage pdf files already in my hard disk, attributing them metadata, in particular TAGS?

There is specific software for that, but either I find it heavy (like Tagspaces) or it obliges you to take notes with a markup syntax, that I find boring. I could use Zotero, but I prefer to reserve it for managing my bibliographies.

I fancy, that what I'd like to do is feasable, but before studying guides and manuals, I would like to know your opinion.

Thank you.
