How do I copy a bank or save it as a file?

Open the bank in My Question Banks. The bank's menu has these buttons:

• ⧉ Duplicate makes a copy in your banks. You give the copy a new title. Use it to make a version for another class without changing the first one.
• ⬇ Export downloads the bank as a .json file. To load it again, press 📂 Import a bank, then Choose a JSON file, and choose that file.
• 🗑 Delete removes the bank. We ask you to confirm, because this cannot be undone.

If a deleted bank comes back, see I deleted a bank and it came back.
