I would like to store movies in the cloud and when on the road use my ipad to download only certain movie files from my cloud and not an entire folder. I only have 16 gb so i need to watch some, delete them and download some more. I don't see how i can do selective syncing of particular files with dropbox, googledrive, or anything else i have seen. Any ideas? Also don't want to have my home desktop on while im away so this leaves out Teamviewer, etc.
