All of your personal data such as downloads, pictures, and videos can be stored anywhere you want. All applications can be installed to a different locations than the default. It is however hard to say what you can move. We do not have a clear picture of what exactly it is you have. We also do not have a clear idea of the difficulty you might have in navigating folders other than default locations.

another question is what kind of backups do you do and why would you want to store them on your c: drive as your post suggests?
Backup are usually done on other partitions or external drives...
