Privacy in homegroup

[DamNatureYouSca]

I want to restrict other users in my home group from accessing MY documents. (C:\Users\*User Name*\Documents)

And only allow other users in the home group to access public folders.
(C:\Users\Public\Public Documents)

I would also like to do this for Pictures, Music, Videos, etc...

Don't share your My Documents folder then.
Open My Documents > Toolbar select "Share with" > Nobody.
