I am trying to free up memory and have generated a list of the largest files.

 

Most of these are videos I have of my students' performances.

 

Some appear to be duplicates, so my question is this:  if I delete one, will that affect the one that looks like it is a duplicate?

 

These are generally ".dmg" files and are also "disk image."

 

Thanks so much!
