Filter and sort

Finished with a project? Use the filters to select the channel and clean up files. You can also sort files by size and recency.

Backup Files

Still need your files? Use our organized backup feature to download your files before deleting them to make space.

Delete in Bulk

Say goodbye to deleting files one by one. You can now save yourself plenty of time and delete files all at once.

Why did we develop flack_?

Because our team needed a solution for the storage problem.

We love using Slack, and like all the other teams around the world, we exchange tons of files over our channels - until we hit the 5GB storage limit.

To make space, we needed to delete files one by one from every channel.

We value our time and thought of a way to make this process more efficient. So we created our own tool and made it super easy for others to use as well and called it - Flack.
