Workspace owners can use basic data retention settings: either keep all messages and files, or delete them after 90 days. When your workspace reaches the visibility limit, Slack will start hiding messages and files older than 90 days to make room for new ones. Files include things such as clips, PDFs, documents, images, screenshots, and audio and video files. You can view and search messages and files from the last 90 days.

Tip: Upgrading to a paid subscription will remove message, file and app limits, plus provide more data retention options. Keep reading to learn more about message, file, data retention and app installation limits. If you’re using a free workspace, there are specific usage limits to be aware of.
