Confluence Attachment limit

[Hsu Yao Chang]

Dear sir, 

Is there any limit for confluence attachment, such type, size...etc? What is  the max size of attachment ? Is there any successful confluence example for company use ? Thank you.

(Just collect the information )

You can limit the size of an individual attachment in Admin -> Attachments.  The default is 10Mb per file.  There's no real maximum size though, and no limit to the number - you are limited purely by your storage in theory (Cloud has a 25 Gb limit by the way)

However, as it's not designed as a large file store, you will find that larger attachments will fail to upload or download correctly.  I usually recommend leaving the 10Mb limit in place, and if you do decide to go higher, never over 100Mb.

Is there attachment timeout limit, such as how long of uploading attachment? Thank you.

There's nothing coded into the software, no. But it's not built for massive uploads and downloads, so anything on your network that interrupts the flow will break it, and there's no recovery mechanism beyond "try again".

@Nic Brough -Adaptavist- Do you have any updates to your recommendations above? I see the default attachment size is now 100MB and the storage limit for Confluence Cloud is 250GB. I'm wondering if you still recommend using the default value and if you have a suggested maximum. Thank you.

[Nic Brough -Adaptavist-]

Yes, I still recommend the default limit.  Cloud has really removed the concern about total space, but the "not a file store" and "struggle to upload/download really big files" things still apply

The defaut size is 10MB. You can configure it though. See https://confluence.atlassian.com/doc/configuring-attachment-size-150040.html

Most file types are supported.
