Mobile account, syncing certain files Under mobile account preferences I have selected "Home folder". What exactly is the home folder and how can I find out where mine is? What else does it include, for example does it include the folder Movies and Images? In mobile accounts is there a way to exclude certain files? 

I forgot to ask but does enabling "sync home folder" mean that only the current user the account synced or all users of the computer have there home direcotry synced?
Your home folder is by default the folder that opens when you click Finder.

It's located at /Users/yourusername and is usually shortened to ~. This folder includes all the folders which contains your data such as Documents, Movies, Pictures, etc.

Mobile account syncing will sync everything in this folder. To skip items, go to Profile Manager → Mobility → Rules → Skip items.
