Determining the Name of Linked Files

I’m sure this is obvious, but not obvious enough for me!

How do determine the name of a linked file? I have a number of simple boxes with different textures linked to each box. How do I determine which file is linked to a specific box?

I’m not as organized as I need to be. Namaste.

Inspect > Properties > Action

(a box displays the path)

Thanks for replying. I’m not having any luck with the solution above. The box you mention does not appear for me. Do you mind posting a screenshot?
Cheers!

with different textures linked to each box

Could you post a screenshot of one of your boxes,
and expand a little on what you mean by linked,
and how the links were created ?
