Ok, I feel like a cloud noob. Ok, Can I use dropbox as a way to have files on my PC and my phone that I constantly use? Can I sync them up so if I change one it changes all? Can these be available offline too? Or would they just be stored in the cloud? All the tutorials I see all seem to just say, "drop a file into dropbox and you can view it on your PC and your phone." I want to be able to view and edit the files on both places. Thanks for your help.
