Opening Files From a Time machine backup

[battlebox56]

Hello, 

I just got done backing up my 2018 macbook pro's data to an external hard drive. I had to back up my data because it is getting serviced tomorrow. I have an older macbook air that I will be using while my Macbook Pro is in service. I use my macbook everyday for school so I Set up my macbook Air off of my time machine back up on my external hard drive. I keep a lot of video files on my macbook pro and I didn't need to move them all over to my macbook air so I kept most of them on the backup drive so I could access them if I need them by externally plugging in the hard drive to my macbook air. Anyways, I tried to open one of my very large video files and I got this error message which will be shown in the image. Any ways on how to fix this?

This terminal command should do it:

sudo chmod -R +444 [location of folder] 

The +444 adds read permissions and preserves everything else. You will need to be an admin to do it.

There is a way to do it in GUI but I can't help with that as my mac was not beer spill proof.
