I am pretty new to Ubuntu (in case that fact is not immediately obvious).
I setup a machine with Ubuntu 14.04 for some people in our church. In setup, I used their user name to configure the computer. Afterwards, I added my name and set it as an administrator (in the GUI). As administrator, I want to be able to see all files that they add or edit. I tried adding root permissions to my account with 'visudo' but that did not give me the access I wanted.
I cannot determine how to grant access to my account for their files. In addition, I do not even have access to the primary partition on the hard drive, or to USB drives that are inserted into the computer. Please explain how I can gain access to view and modify their files, and how I can access the primary drive and USB drives that may be added.
The drive partition and USB drives are listed under media/firstuser. The firstuser folder is owned by root. I added my user name to root group, but still cannot access the firstuser folder.
And since appreciation is not to be added later, thank you in advance. :-)
