The default is 10Mb, but you can change it in Admin -> Attachments.  Don't go too large though - Confluence isn't designed to be an upload/download manager or a file repository, and you can get timeout problems with very large files.

Nic, what do you find to be a tolerable maximum? We - large instance with 10's of thousands of pages and attachments - have had it set for years at 100MB with no issues.

I've not seen anything significant up to 100Mb, so that's the highest I tend to set it before I start resisting the requests for higher amounts with any gusto. 250Mb is the point at which the problems tend to start in my expericnce - it's where I start telling people to use proper file storage and not to rely on being able to attach or read files with Confluence.

Oops, I also wanted to say that it's on a file-by-file basis - doesn't matter if you've got hundreds of thousands of large files, it's just that for any one selected large file, you can run into upload/download problems. Most of the time, even much bigger files will work. You just can't *rely* on the upload or download working.

Nic, Thanks for the insights - appreciate the full explanations as this was a topic I had wondered about for a while as I have received requests to raise it too. We started at 50MB, raised it to 100 MB and I think will stop there. :-)
