ES File Explorer is an highly rated free Android File manager supporting a large range of file/data connection types.
In the network(Net) section Skydrive access is now supported along with Dropbox, Box and Sugarsync
I guess Google Drive will be the next storage app to be supported. ..some time..
For myself, I find the LAN accessibility to be a true boon when it comes to file access to and from my NAS using ES File Explorer.
