Your archived data will come in the form of a zip folder. Clicking the Your archive link will show you an HTML document with an interface that’s similar in aesthetic to that of the Twitter platform itself. This file holds all of your account information up until the moment the archive was requested.
You can view account information, Tweets, likes, direct messages, blocked and muted accounts, personalization data, lists, and more. Note that this file is for reference only and can not be used as a backup to restore data to your account.
