How to increase limits on activity attachments?

Question

Current (4.6.7) limits say that an activity can have up to 3 attachments, each being less than 2MB.

I need more, and a bigger file size limit.

What are the obstacles to achieving this?

• I can't see anything in the db schema that implies a limit per activity, so is it just the UI that imposes the number of file limits?

• The files are stored (I assume) in the civicrm_file.document field which is a MEDIUM_BLOB and can therefore store a file just under 4GB. (my requirements are only ~20MB.) Is that 2MB limit set in a PHP ini file?

Thanks.

Answer 1

Go to configure it in your settings /civicrm/admin/setting/misc?reset=1

Answer 2

As a side note you might also need to increase PHP limits for larger files
