Move folder from old hard drive to new app

Motherboard on my old computer, using eM Client, went bad. Computer repair got me a clone of my old computer and the old hard drive wouldn’t start it, so they put the old hard drive installed as a secondary HD. I have some important emails stored in the Local Folders that I’d like to access. How do I find these on the old HD and get them to eM Client, I’ve already installed or can reinstall on the new HD if needed?
Thank you!

With eM Client closed, you need to copy the C:\Users\yourusername\AppData\Roaming\eM Client\ folder from old disk to the new one. You may have to enable hidden items in Explorer to get there.

That is default database location, but if you had it in another location on the old disk, then copy it from there instead.

Delete the entire new file and replace with the old or add to the new?

Delete the entire contents of the eM Client hidden roaming folder on your new hard-disk and then replace it with your old eM Client hidden roaming folder contents as @Gary advised above.

Then once done, open eM Client on your new computer & it should then work fine.
