Memory stick help

Hi All.
I have a new Holland T7.210 and have just started using memory stick to save fields from tractor monitor to usb stick.
It all seemed to work but when I have put in laptop to download I see loads of files but they all seem to be random numbers and letters .
Being a bit of a techno learner just wondered if I need certain app to open files to show fields.

Any help would be appreciated. Thanks
