How to find out where the script is used?

Hi,

Is there a way for me to identify where a script is being used other than identify from script name and description itself (unreliable since sometimes there's no description and badly named name).

In specific, I would like to know where this script is used: IMPSCSS

Would want to know where it is used since I noticed, in production folder, there is an entry in script dictionary but no description.
