300 Mb limit confusion

Hello,

Despite going through the documentation and several threads on the forum, there is still something unclear about how Zotero stores files.

I am coming close to my 300Mb limit, and wonder about solutions to free some space because of warning messages I received.

1) What is taking up all that space? I thought that files/pdfs were not stored in Zotero, but in the Firefox subfolders on my hard drive.
I confirmed this by trying to access PDFs from a different computer, and it said the file wasn't findable.

Does this mean that some files get stored in Zotero, and some not (I didn't check my files systematically)? I now unchecked the file syncing option, but still wonder it there is a way to make more room with th 250+Mb i already have.

2) Is there an option to see which files are stored in Zotero? Is there a way to explicitly store a specific file in Zotero, so that I could access it from any computer?


Thanks for any clearing up regarding these storage issues!
  • 1) File syncing refers specifically to attached files (pdfs, snapshots etc.). Nothing else fills up your storage quouta.
    The files are stored locally _then_ synced. So disabling file sync will _not_ stop Zotero from adding more files locally, it just means they won't sync online and, to the extent that's relevant, to other computers.
    Not sure why you couldn't access the file on the other computer
    See here for troubleshooting: https://www.zotero.org/support/kb/files_not_syncing

    2) no, you can't sync selectively and Zotero can't easily show you which files are synced.
  • Thanks, this was helpful!

    You were right, I just had bad luck as the few elements I tested were unavailable for some reason, but I just tried a couple others and could access the PDFs from within Zotero. Now it all makes sense :)

    About point 2), is there nonetheless a way to delete the synced files without deleting the ones stored locally on the drive? Or is the only solution to delete the entire element, and re-cite it with the file syncing option disabled?
  • Re 2) neither of those options work. There really is no way to selectively sync attached items, not even with complicated workarounds (well, technically you can link some items, which won't be synced, and then sync only attached items, so I guess that might count).
    If you don't need file sync, disable it. Otherwise either pay for more or use webDAV.
  • Thanks again. But maybe my last point wasn't clear: I wasn't talking about selective syncing, but rather of a way to delete attachments from within Zotero.

    My concern is now to remove a couple files from Zotero, just to be on the safe side and not so close to the 300Mb limit. I assume with the file sync option disabled, storage will fill up quite slowly, but as I don't know actually how much space a citation with metadata can weigh, I'd rather have some margin.

    Thanks therefore if you have a method to remove files from Zotero, otherwise I'll just hope the amount left will suffice for a couple more years :)
  • With file syncing disabled, you will never go over the storage quota. It won't fill up slowly, it will just not fill up at all.
    Metadata synced doesn't count towards the 300MB it's free regardless of size.
  • Ok, thanks for confirming this!
