Archive mode works similarly to regular tweet deletion. The difference is that you also supply us with your Twitter archive file. This contains a full list of your tweets, so we can use it to find and delete any number of old tweets (avoiding the 3,200 limit).
Before you can use archive mode, you need to request your archive file from Twitter. You can do this by pressing the "Request your archive" button on the "Account" page of your Twitter settings (as shown below). Make sure your Twitter email address is also up to date, so that they can email you a link to the archive file.
The process is slightly different in Twitter's mobile apps. Please refer to Twitter's instructions on downloading your archive for your particular platform.
Once Twitter has prepared your archive, they will send you an email link or a push notification allowing you to download the archive file to your device.
Once you have your archive file, simply fill in our archive mode form. You'll need to press the "Browse" button and pick the Twitter archive file you just downloaded.
Please be very careful to also specify your tweet age and keyword settings correctly, as archive mode is capable of deleting all your tweets with no limit.
We preserve your privacy by deleting your Twitter archive file from our servers immediately after we process it. This is before the tweet deletion even starts (we use ID numbers for that and don't need to store the actual tweets).
We can work with any one of the following files in archive mode: -
Some users have reported getting a different version of Twitter's interface that doesn't have a button to request your archive, and only allows requesting Twitter data. In that case the best option is to get your Twitter data file, extract it, and submit the "tweet.js" file it contains.
