When I right-click on Documents, there is no option to add a new folder.

Under Devices in Finder, I left-click on David's Mac mini then Macintosh HD > Users > MyfirstMac. If there were more users, how would they show up in Finder? In Finder, why is there a Favorites section? Why is it called Favorites? When I click on Desktop, the path is Macintosh HD > Users > MyfirstMac > Desktop. That's what I want to do with both of my Macs. Then I manually saved my personal stuff in subfolders. When I had Windows, I created a shortcut for the Documents folder on the Desktop. Either way, I want all my stuff in a centralized location so that I only need to back up one folder & all of my stuff would be in subfolders. I can do it manually or I can use backup software.

I already manually back up stuff that I want to save. I just want to back up my personal stuff. I don't want to back up Applications, Downloads & Desktop. If I were to back up the 'MyfirstMac' folder, it would back up Applications, Desktop, Movies, Music, Documents, Downloads, Pictures, whatever. Is that equivalent to a shortcut in Windows? I noticed that the path is Macintosh HD > Users > MyfirstMac > Music. When I left-click on 'MyfirstMac' under 'Favorites' & then right-click on 'Music' in the Finder, one of the options is 'Make Alias'. I want a centralized folder for saving all of my stuff. I'm ripping my music CDs & I want to save them. I might want to learn Objective-C, so I'll want to save the demo programs. I'm learning Java so I want to save the demo programs.

Time Machine only does full backups & incremental(or is it differential? I get the 2 confused.), right? I can't specify specific folders for Time Machine to back up, right? I have text documents that I want to save.

I thought about it after I sent the post, & I'd rather back up personal stuff than the whole hard drive.
