I know that deleting the old build that still resides in my local drive on my SP3 will give me more breathing room... Is it possible to move those files pretaining to the old build to my SD card and still have access to it if I want to roll back to windows 8 just in case? I am having some problems with my surface (realy some minor ones) that I think would be solved with a larger drive space. I currently just have 13GB free on my 128gb SP3. The main problem I have is that I cannot sync all of my one drive files because I need more local space. anyone?
