# Copy pp5022.mi4 to the root of your device
# Copy OF.mi4 to the "system" folder within your device (make sure you have set Windows to "Show hidden files")
Some questions who's answers might help you get some help:
- So you managed to copy pp5022.mi4 but it's giving you problems with OF.mi4?
- It's the SYSTEM folder that's read-only?
- Perhaps you're not logged in as Administrator and that's why it doesn't allow you to change the setting?
- What operating system are you using? (Linux/Windows/OSX/etc)?
- What is the exact error message you are being given?
