Do you interpret that sentence to mean you can rename a folder?
Read it like this:
Use copy
Use rename
Or replace operating system files and folders
RC is limited, but useful. Renaming a folder is not within it's
powers.
If you are replacing a MB, and want to use your original HDD, you
should have said so. There is a process for doing that but it has
nothing to do with RC.
Do you need to a good article that describe the best way to replace a
MB into an old working XP environment, or are you well on your way
with the information you have?
