Frequently Asked Questions
While .anki files are essentially SQLite databases, direct editing outside of Anki is complex and not recommended. It's best to use the Anki application for modifications to avoid corrupting the deck.
You can export your deck from Anki (usually as an .apkg file, which is a zipped version of .anki) and share that file. Alternatively, if you both use AnkiWeb, you can sometimes share decks directly through the AnkiWeb website community features.
Spaced repetition is a learning technique where you review information at increasing intervals, helping to combat the forgetting curve and improve long-term memory retention.
Technical Details
Anki deck files are essentially SQLite databases that store flashcard data, including notes, fields, card templates, and scheduling information. They are typically compressed using zstd for efficient storage and faster loading. The internal structure allows for flexible note types and custom card layouts, making them highly adaptable for various study needs.
