The documents in zotero suddenly disappeared automatically.
I'd like to ask everyone for advice. My zotero is installed on a portable hard drive and I haven't logged in to an account. I usually import literature from article web pages using plugins. When I opened it today, I found that all the literature I imported since last week was gone, and even the folder I created last week was gone. But the literature and folders I imported before are still there. Does anyone know what the reason is?
Since I downloaded it to the portable hard drive from the very beginning, I also customized the data storage location to the same folder on the portable hard drive. I have now moved the installation directory and the data storage location to drive D.

Upgrade Storage
For what it's worth, your .bak file, which should be recreated every 24 hours, is from mid-November and is likely an empty database, which suggests that this isn't the data directory you've been using. You could also check whether there are folders in 'storage' from earlier dates or if they're all from today.
