I saved the hidden folder .mozilla-thunderbird from a linux install many years ago. I just found it while cleaning up some hard drives/data and would like to import all the mail folders I had from them and take a look and see if any of it's important. I don't have any of these accounts anymore, but I would like to browse through and make sure I'm not losing something valuable. I tried copying the folders into C:\Users\James\AppData\Roaming\Thunderbird\Profiles\dzsvmhws.default but I don't see any of it in Thunderbird. I tried copying them to the local folders folder, and the folders showed up in Thunderbird, but were empty. Any ideas?
