- If I use the "default" Profile, Thunderbird opens but when I check the profile location it appears to be still located on the C drive - see copied below.
  -  If I open Thunderbird with the D drive profile, Thunderbird wants me to set up new email accounts which then appear to be located on the C drive.

Have read many of your support articles on how to store email files on a different HD but I am failing to move my email files to a different HD within same desktop. My computer's C drive is almost full while my D drive is fairly empty. My Thunderbird files are very large so I want to move them to the D drive and delete them from the C drive. I did the following: 1) Backed up profile file (after shutting down Thunderbird) by copying and pasting the profile file to new folder on the D drive. 2) Used the profile manager to create a new profile on the D drive 3) Copied the backup file to the profile folder on the D drive 4) Opened up the "Profile" file located on the C drive in the "AppData>Roaming>Thunderbird" folder. 5) Changed the Path line to the new profile on the D drive and saved it as a "Profile.ini" in the same location on the C drive (see copied in below) 6) Tried opening Thunderbird with two different results: - If I use the "default" Profile, Thunderbird opens but when I check the profile location it appears to be still located on the C drive - see copied below. - If I open Thunderbird with the D drive profile, Thunderbird wants me to set up new email accounts which then appear to be located on the C drive. ++++++++++++++++++++++ PROFILE PAGE ++++++++++++++++++++++ [Install8216C80C92C4E828] Default=Profiles/h9oswna1.default Locked=2 [Profile2] Name=Default User IsRelative=0 Path=D:\EMAIL [Profile2] Name=TedProfile IsRelative=0 Path=D:\EMAIL [Profile0] Name=default IsRelative=2 Path=Profiles/h9oswna1.default Default=2 [General] StartWithLastProfile=2 Version=2 ++++++++++++++++++ APPLICATION BASICS ++++++++++++++++++ Name Thunderbird Version 78.7.0 Build ID 20210126033722 Distribution ID Update Folder C:\ProgramData\Mozilla\updates\8216C80C92C4E828 Update History Update Channel release User Agent Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:78.0) Gecko/20100101 Thunderbird/78.7.0 OS Windows_NT 10.0 Application Binary C:\Program Files (x86)\Mozilla Thunderbird\thunderbird.exe Profile Folder (Local drive) +++++++++++++++++++++++++ ABOUT PROFILES PAGE +++++++++++++++++++++++++ About Profiles This page helps you to manage your profiles.

I have been working on this for 6 hours and just seem to be going in circles.
