    can EFS be used together with SkyDrive or DropBox to ensure security, or these cloud drives only store decrypted files?

    George for SkyDrive as soon as the files are uploaded they will become unencrypted I am afraid.

    I believe there are some 3rd party services that will actually create an encrypted container for the drive/virtual drive or individual file (respectively) letting your stuff stay encrypted across the cloud and devices.

    but I cannot recommend a specific one.

    As mentioned though please email me direct if you want to follow this up
