I have given up on IFW: too complicated for me, for my simple use. Thank you bbearen and Paul T for all your efforts.
I tried Minitool too: it failed in backing up all .pst, .nst and.ost files in /users…/AppData/…Outlook !!
I am trying Macrium Reflect 8 on both pc’s. On the Win11 pc, I noticed a reference to Bitlocker again. I have no idea what to do with this, not its purpose, nor if I even need it. Can I get rid of it? How without affecting everything else?
