I had a deck of around 250. I pressed sync and download from ankiweb, and the deck disappeared. I can’t find it. I’ve looked online to see if people have had similar problems, and I still can’t figure out what to do. How do I get the deck back?
If you selected “download” when the “one direction sync window” popped up, your data was overwritten. You may recover it using a backup.
Makes sense, thanks. I did that, but it wants to overwrite my currents decks. Is there a way to restore while keeping the decks I have right now?
You can export each deck that you may have right now:
Then restore your data and import the decks exported previously.
