i might be a dummie, but i still don't quite understand the syncing principle
Sorry, I'm a beginner, so my question may sound stupid, but I just don't quite well understand the sync principle. In my limited understanding the database is on line, and you access and work on it through Firefox, so what is there to sync with physical computers then?
As I mentioned above this model has the considerable advantage that you can continue working if you don't have access to the internet (e.g. at a library or during an outage).
P.S. With the release of Zotero standalone you don't necessarily need to use Firefox to work with Zotero if you prefer another browser.
For file syncing (which is non-free for >100MB with Zotero file storage) you can use any cloud-based service that offers WebDAV.
