My desktop PC video & audio died, so I installed the disk drive into a new PC as its 2nd drive. How can I copy my old TBird data from the 2nd drive to the 1st?

My old desktop PC video & audio died, so I installed the C drive into a new desktop PC as the 'F' drive. How can I copy my previous TBird email & addresses from the F drive to the new TBird location on the C drive? btw - I'm surprised that the fix for this common occurence isn't already in the on-line troubleshooting info.

The Thunderbird folder described above contains a Profiles subfolder, which in turn contains the profile folder(s), which contains all address books, mail, calendars, add-ons and account settings. There will be separate Thunderbird folders for each Windows username, as indicated in my first reply.

Transfer the Thunderbird folder from the old drive to the new drive:

The Thunderbird folder is located (by default) here:

C:\Users\username\AppData\Roaming\Thunderbird\

According to the TBird website, the Emails & address book aren't stored in the Thunderbird folder, but rather in the 'profiles' folder. This seems to make sense to me, as there may be multiple users (a.k.a. profiles) on a PC, but they only need one code set per PC.

You were right, of course. The problem was that those are all hidden folders & files, & I hadn't yet enabled display of hidden items on my new PC. Once I did that, it all became clear. Thanks for your patience!
