How to view linked files and change links?

Background:
I am working with large presentations (with many videos). I prefer to link videos instead of embedding them, otherwise files get huge!

I always copy videos/images into same folder as my presentations. For a new presentation (usually progressively improved version of the previous one), I make a new folder. This helps to keep things organized.

As I need same files again and again, I would like to reuse videos from previous presentations. When I copy the previous presentation into another folder, reference links to videos are broken.

Actual Question:
Is there any way to fix broken reference links to videos in the impress user interface?

No way! You can work around the problem if you leave all videos and presentations in the same folder.
