You can upload any number of attachments in any format, and each one can be up to 200MB. There is no limit. I used this to great effect when I still used Patreon to host FLACs of all my music for supporters in zip archives split in 200MB volumes.

I replaced it with a simple Ko-fi shop where you can just upload anything up to your 200GB quota (if you're a Gold member): https://ko-fi.com/s/7e9f22c63b
