Ruby- Issues with opening an image using .system and .exec : My goal is to make a program that can open image files in the default image viewer (in this case, the Windows 10 Photos app) and close them again at specific user input.  
  
The following line has been giving me heaps of problems and confusions:  
`Kernel.system('full_path_to_image')`  
I attempted the same with `.exec`, but it simply returns the format error (Errno::ENOEXEC)  
Simply entering the file path as a command into the Command Interpreter works just fine, even if it's done by using `Kernel.system('cmd')` to open an instance of the intepreter, _then_ entering the file path.  
I've read some other answers to questions that talked about shell expansion, and avoiding the shell entirely by using the multi-argument version of `.system`, but I couldn't get that to work and I feel that I'm missing something obvious, or doing something wrong here.  

Is it even possible to do what I want to do?  
(If the info is of any use, my file path contains backslashes, not standard slashes, although replacing them doesn't seem to change anything anyway.)
