Ask users where they would like files to be stored and apps saved
My computer has multiple hard drives, the small system drive (C) and the large data drive (D). The problem is Adobe CC saves everything to C thus rendering it full and blocking OS updates.
It shouldn't require the user to jump though hoops to change this, if it is even possible. When the user installs the app ask them where they would like files to be saved to.
Then they can either choose to go with the default location (C) or choose where they want files to be saved and then don't save files onto C anyway regardless of user choices. Given that users will be using Creative Cloud a certain level of technical experience is expected. This has been causing me a lot of problems when C is full.
