How to use a modded save file?

I'm a bit new to using modded save files. I downloaded one to use in Diablo 3 but I don't know how to use it. Please help.
Pardon my ignorance I hope you understand.

 

To move a gamer profile from a hard drive to a USB flash drive:
1. Plug the USB flash drive to the Xbox 360 console.
2. Move to the System section of the Xbox Dashboard.
3. Select Memory, and then press the A button.
4. On the Storage Devices screen, select Hard Drive, and then press the A button.
5. On the Hard Drive screen, select Gamer Profiles, and then press the A button.
6. On the Gamer Profiles screen, select the gamer profile that you want to move, and then press the A button.
7. On the Individual Gamer Profile screen, select Move, and then press the A button. You'll receive the following message:

Before moving a profile, the profile must be signed out. Are you sure you want to sign out and move this profile?

8. Select Yes, and then press the A button.
9. On the Select a Device screen, select MU, and then press the A button.
10. On the Storage Devices screen, press the B button to return to the System section.

How to move Gamesave onto USB:
11. On the Hard Drive screen, select Gamer and Apps, and then press the A button.
12. On the screen There will be all the games on your Xbox360, select the game that you want to mod, and then press the A button.
13. On the screen you will see all the Saves, choose your gamesave, and then press the A button.
14. On the Individual Game Save screen, select Move, Choose the USB then press A.

 

That didn't exactly help me but I'll deal with what I got.
