Is the way to save the new file by caching?
I hope to be able to ask this question to the relevant technicians. Have the newly added documents and operations been temporarily stored in the cache before being saved? After adding two subfolders to the documents, I performed a computer junk cleanup operation. After that, the newly added documents disappeared, and the names of the two subfolders that I had modified were also reverted back. Could this be because the software I used to clean the computer junk deleted the newly added documents in Zotero under the guise of being a cache?
Upgrade Storage
There's really nothing else we can tell you here other than to make sure you don't let your disk-cleanup programs delete zotero.sqlite.
