32-bit to 64-bit

Okay, short asking, will my datas from C: and D: be backed-up if I change my OS from 32-bit to 64-bit?

There is no upgrade/downgrade path. You must do a clean install of the OS. If your data is on a different partition than the OS, then yes it's safe, otherwise, no.

So I must re-install all of my program if my OS and program files partition is same? And how do I know the partition details on my PC?

You have to reinstall all your programs regardless of partition. You asked about your data (pictures, videos, documents,...), not your programs.

Oh, it is a hard decision, then. But thanks for the answers. It really helps.
