How do I use SkyDrive to free up some space on my P.C.?  I now have twice the storage space used on my computer  ie: Documents Folder is now also using same space in SkyDrive/Documents Folder. I don't share everything with Sky Drive so I'm very confused...why do I need two of the same folders in my computer? Should I work from the SkyDrive documents folder or my original documents folder?  Can I delete files from computer and leave in SkyDrive somehow without them being anywhere on my computer?

AND....can a hacker access my sky drive?  I have been embarrassed enough already when a hacker got ahold of all of my contacts and sent Viagra ads to them all FROM ME.  Boy did I have some explaining to do. Most of my elderly contacts (like my mother) couldn't grasp the concept  of my being hacked...I think they still believe I sent them...   :-l
