Hi, this looks awesome but where can I download the tool?
You need to go to sourcecode link on codeplex and download the zip from there.
Looks good, but is there a way you can reverse the functionality?
So from the perspective of a JavaScript file, see all the forms and events that are dependent on it? That way you can see if you need a JavaScript file in the solution anymore.
Hi Michael,
The option you need is available in XRMtoolbox, web resource manager.
