I have a flash drive with all the files from my old PC. How do I access / find this flash drive after it is installed, and can I save and use these files (Microsoft Word, Excel, PowerPoint, Outlook primarily)?
Accessing Flash Drive
You have a number of options here:
I'm going to assume you are talking about finding it in Terminal and not Finder as you asked about access /.
That will put you in the / directory of the flash drive. If you don't know the name of the flash drive.
Then do a ls. Your flash drive should be listed. You could also find the name of the flash drive listed in Finder.
