# Working With File Attachments

> Learn how to upload, manage, and delete file attachments.

## Upload a File

Files up to 5MB in size that are attached to Slack messages will be synced to the Tightknit community site.
They will appear as attachments on the corresponding post or comment.

  files larger than 5MB.

### Blog Cover Images

For Feeds that are configured to [display posts as "Blogs,"](/community-site/pages#blog) the cover image used is the first image file attachment on the Slack message, if any.

## Delete a File

If a file is attached to a message and the message is deleted in Slack, or the post/comment is removed from the Tightknit site using the message shortcut, the file is also deleted.

You may also use the `Delete file` action in Slack. This action will only delete the file in Slack and in the Tightknit community site, and the post/comment will be preserved.
