OK, ater a few minutes of posting my previous reply, i tried again and this time I did find "About Profile"....the reason I did not see first time, it seemed greyed out...regardless, now again your instructions get a little confusing...you say that once i create a profile i should choose another name, which I did...and finishing I saw both profiles, the existing small one and the replacement that I wanted, but I did not see the one that u recommend to rename again, so I picked the one I originally renamed with all of my past TB info, clicked Finish. Now i am nervous to check it out to see if it worked, cause I am expecting a very important email overnight and do not want to risk on not being able to get it. Once i get that email then I will try...thanks for now.

Scrolling down this thread i see that the very latest post I sent last night is not shown here..so i will do a little repeat here. Like that saying goes,"getting close, but no cigar". I left with my profile old is finallyshown in the trouble shoot layout, where it says that it cannot be deleted. This morning, I opened TB, troubleshoot default and now the Profile that appeared last night, was not there...one of the other one. I want to get some comfirmation from you...about import/export mode. Are you saying i should go to the destination pc, import from there? I opened my old profile and clicked on Properties and it showed all the files of 2.1 gb...if that means any thing.

I am puzzled on your problem, as copying in a profile is a simple process. Since you're having difficulties, but seem comfortable with windows file explorer. let's try a simple, non-thunderbird approach. - exit thunderbird - locate the active profile, which you should know from my prior posts - copy the profile elsewhere, anywhere that's safe and can be returned to if needed - copy the contents of your old profile and paste into the active profile folder. - restart thunderbird.
