Twitter CEO Dick Costolo told reporters of The New York Times that the microblogging site is developing a new tool that will allow users to download a file to recover all their previous tweets.
Costolo said, "We're working on a tool to let users export all of their tweets. You'll be able to download a file of them."
He further added that while users will be able to dig through their own tweet archives, there are no promises of a feature that will allow them to access all the tweets posted to the site from every user.
Currently users can only search for the last few thousands of posts. Other third-party sites like TweetSaver backs up most of a user's tweets along with private messages and replies from other users. But it's a paid service.
