Zotfile is no longer being developed and is not compatible with Zotero 7.
If you are a Zotfile user, the set up and functionality of ZotMoov is exactly the same as Zotfile. You'll need to download ZotMoov but you can use the same directory you were previously using for Zotfile, and do the same for the Linked Attachment Base Directory. The instructions below will walk you through the process.
ZotMoov should not break any existing links, but, just to be careful, we recommending making a back-up of both your Zotero Library and the cloud storage folder that you'll be using.
