Corrupted and unreadable files
Hello, my Zotero stopped retrieving my pdf files recently. When I went to look at my sources for my latest paper, every file I have on Zotero says that the file has become corrupted and unreadable. The reference information is still there, but I cannot view the article pdf. I tried updating Zotero, restarting my computer, and restarting Zotero. When I tried to put new files into Zotero and these new ones did the same thing as soon as I tried to open them in Zotero.
You'll need to repair your disk outside of Zotero.
