Hi,
I have experience in web development and worked with various products of Atlassian including Confluence, JIRA etc. I have developed plugins for them based on the need.
I will explore the possible ways to block the download for a particular space. I can override the existing download feature with my new code to block the download.
Give me the version of Confluence you use, so that i can do setup the development environment and work on to deliver for live.
Thanks,
Rishi
