Treat certain file types as text when attaching to an issue

Question

When you upload a .txt file to JIRA when you click on it the file is displayed in the web browser (not downloaded).

However if you attach a .log file or a .crash it is treated as a binary file and downloaded. How can we update JIRA with a list of known file endings that are actually text files and should be treated as such?

Thanks for the reply 
 It might be an idea to add things like .crash and .log to the plaintext defaults?

Edwin,

You have to edit the mime.types file located at JIRA-INSTALL/atlassian-jira/WEB-INF/classes so JIRA knows what files should be plain text.
