I've heard of zotero maybe a year or so ago, and was curious about it, but never took the plunge. I manage the bulk of my info/knowledge base across mostly locally-saved text files, with a few other tidbits leveraging PDFs and word process files (.odt, .docx)...and really i only use the latter for pasting in screenshots. And, then of course simply synching them across devices using syncthing.

While my approach works great for the majority of the time, i can imagine there might be some functions that some other tools might bring me which i might be missing...I suppose one thing that i lack is a graph of linkages for content that might live in different, separate files but might be related, etc. So, would you be willing to share your opinion, experience for what makes zotero better than text files on a disk? :-) Thanks!
