[tutorial] How to delete review history to a card

[addons_zz]

First close your Anki application if it is running, backup your Anki collection file.

Then, as stated on the post https://anki.tenderapp.com/discussions/ankidesktop/27839-is-there-a-way-to-reset-anki-card-info-from-browse-info, you can delete all the history of a card using the addon https://github.com/ankitects/anki-addons/blob/master/code/removehistory/init.py or directly opening the Anki database and accessing the revlog table using https://sqlitebrowser.org/.

The advantage of using https://sqlitebrowser.org/ is that you can delete only a few entries, instead of everything.

Schedule info in exported apkg file

What scheduling information is included in an exported apkg file (when the “Include scheduling information” option is selected)? It appears that the status of a current day’s studying is not included, for example, that I may have already studied some number of cards.

After making any such changes, you’ll also need to force a full sync.
