As two file names include "protected", probably to make any change you
need to "unprotect" them first. Is it possible and allowed?

Other than that, the "file" command can tell you a file type.	

For instance type:
file asimovs_2018-11-0001.3gp

If it falls in the "text" category you can display it in a pager like
less, most or more. 

Knowing the results can maybe help someone help you.
