Missing files in Zotero library
So I didn't use zotero for almost a year, I downloaded it to my work desktop and found some missing folders in my library. Basically nothing over the past 2 years. I've tried many fixes including. I use it with chrome. I'm not sure whats happening but its making me panic. Now my macbook isn't showing the folders either
Again, you haven't uploaded any data to your online library in the last two years. If you sync a new computer, you will just get the data in your online library. If you want access to all your data, you need to actually sync the computer where you added the data originally, which you haven't done in the last two years, so that it uploads the data to your online library and makes it available to other computers.
The only way to get that data on another computer is to use Zotero syncing.
You were using Zotero and the Word plugin on a different computer from the one you're using now, and that computer has not synced in the last two years. You can look at your online library on this site to see that you have no data since early 2018.
If you set up Zotero on a new computer and sync, all you'll get is the data in the online library, which in your case goes through 2018.
If you want your more recent data, you need to sync the computer where you added that data. Once that data is in your online library, you can sync Zotero on any other computer and have that data in your local library, which will let you use it with Word.
