Follow these instructions. http://kb.mozillazine.org/Moving_your_profile_folder_-_Thunderbird#Create_a_new_profile_and_copy_the_old_one_over_it

I tried to run the Profile Manager, but I got this error message: "Windows cannot find '-profilemanager'. Make sure you typed the name correctly and then try again." Any ideas why it can't find it? Thanks

I looked at someone else's question about moving mail folders from Windows XP to Windows 7 (which is what I'm doing), but the suggestion is to read this article:

http://kb.mozillazine.org/Combining_two_profiles,

which talks about SeaMonkey (I have no idea what that is). That article refers to this:

http://kb.mozillazine.org/Importing_folders

but it talks about Windows 2000, so I wonder how old it is. The articles don't have a date on them, so how can you know if the instructions work for Windows 7?

Windows cannot find '-profilemanager'.

What is the exact command you're trying?

I tried: -profilemanager

and it didn't work. I also tried the path + that, and it didn't work, but today I was able to get it to open (I was missing a "(x86)" in the path).

I'm trying to backup my profile with MozBackup, since I hadn't tried that yet. I'll see if that process works.

Thanks!

in your new Thunderbird. Select troubleshooting information on the help menu. Select the show folder button in the profile section.

Windows Explorer opens in the folder Thunderbird is now using as your default profile.

If you copy the contents of your old profile into the new one with Thunderbird not running then is will just be there when you open.

Conversely, you can to copy the %appdata%\Thunderbird folder (which has your profile as a sub folder) from the old to the %appdata%\Roaming\Thunderbird folder on the new computer.

Access the location by typing %appdata% in the start menu and pressing enter. Windows will locate the correct physical location it is using for application data and open windows explorer at that location.
