Sometimes, you may want to move Thunderbird profile to another location or make Thunderbird use a profile located in another address. Then, you have to redirect Thunderbird to the new profile.<.p> Close Thunderbird. Move the profile folder to the new location. Locate the profiles.ini file (C:\\Users\\\\AppData\\Roaming\\Thunderbird\\) and open it with a text editor. Locate the entry for the profile in profiles.ini and change the Path= line to the new location. If you switch from a relative path to a non-relative path, you may need to change the direction of the slashes within the path. For instance, in Windows, relative paths use forward slashes while non-relative paths use backslashes. Also, you need to change IsRelative=1 to IsRelative=0. Save the changes and restart Thunderbird.
