How to see what is on the WD external hard drive

I have 2 questions: I just did a backup of the files on my PC on WD My Passport external hard drive. How can I view those files on WD My Passport (how do I know exactly what is on WD My Passport)?
Also, can I plug WD My Passport into my laptop and transfer the PC’s backed up files to laptop?
Thanks.
