How to make a custom link linking file paths to work items?
Accepted answer
You ask this because of https://jazz.net/forum/questions/258604/how-to-attach-or-link-artifact-in-work-item-as-file-path-rather-than-file
So here my 2 cents.
1. You can not use the attachment part of the work item editor presentation, as that is basically not build for that. Create an enhancement request, if you like.
2. Using File paths might or might not be working, because browsers don't allow local file paths for security reasons any more.
3. You can use add related artifacts to link to any URL. You can try to add your file path there, if that does not work, publish the files using a HTML/FTP URI e.g. store them in Artifactory or publish the location using a Web Server.
4. If you want to create a custom link type look at how the Related Artifacts is implemented by looking at the plugin in the RTC SDK. See https://rsjazz.wordpress.com/2014/12/03/creating-custom-link-types-for-rational-team-concert/
5. You can also drop URIs into comments and descriptions to get a mentions relationship.
