What is this downloaded message storage data used for?

The downloaded message storage data, often a compressed file, is primarily for your records and viewing outside of the Messenger app. It’s not typically designed to be re-imported directly into your live Messenger chat history to make old conversations reappear in the app.

You can usually open the compressed file on your computer to view your chat history and attachments. The content is often in a readable format like HTML or JSON.
If you are trying to restore end-to-end encrypted chats to a new device or after losing access, Messenger uses different methods that rely on cloud backups (like Google Drive or Apple Account) or one-time codes, rather than importing a downloaded file.

Here’s how you can restore end-to-end encrypted chats if you’re setting up a new device or have forgotten your PIN:

• Using a Google Account (for Android) or Apple Account (for iOS):
  • When you log into Messenger on a new device, you might be prompted to restore your chats.
  • Select the primary Google Account (Android) or Apple Account (iOS) you used to set up your device and allow Messenger to restore.
  • You would have needed to have “Save key in Google Drive” (Android) or a similar setting (iOS) enabled previously.
• Using a one-time code:
  • If you’ve forgotten your PIN for end-to-end encrypted chats, you can use a one-time code to restore them on a new device.
  • When logging in on a new device, choose the option to “Use a one-time code instead.”
  • A code will be sent to another mobile device where you’ve recently used Messenger.
