SkyDrive is a pretty cool free app with a fair amount of free storage, but I really don't want to sync files by dumping them in the SkyDrive folder - so...

I tried simply making a soft link to the folders I wanted sync'd on my drives and it turns out that it works just fine.

mklink /D "C:\SkyDrive\MyFolder" "C:\SomeLocation\MyFolder"

You need to be running a command shell with Administrative privileges before you execute that.

The example above presumes that your SkyDrive folder doesn't already have a "MyFolder" link or folder in it, and when it runs, a soft symbolic link will be created in the SkyDrive folder that resolves to the actual folder location outside of the SkyDrive.

I currently share files between two PCs and an OSX box (yes, SkyDrive is on OSX too) this way before they qualify to be put into source control...
