I want to work on a folder on my System Drive. I need to combine several SeaMonkey mail folders and want to try a strategy offered on the Mozillazine SM forum. The folder is:

C:UsersMyNameAppDataRoamingMozilla

I've been advised to 'copy the folder to another location' before undertaking the work.

I've set up a directory:

D:ZTW_TempMozillaProfile031019

on my data drive.

What's the most straightforward way to create a copy that I can copy back to the System Drive if I my efforts do not work out?

thanks,
John
