Hello there Plowmail

We have read your message We try to help you.

Windows 7. The top level of the directory is the root directory. Looks like it has expired?

Are there any complaints you have with the operating system? concerns windows 7 or Thunderbird? Only the folder is gone.

Windows 7 outdated.

it's an old webpage but helpful

Has the computer also asked for certificates? Or encryptions lately?

Thanks very much for your response. However, my issue is not with Windows. Rather it is with Thunderbird configuration. In "Help->Troubleshooting Information/Profiles about:profiles", the value for Root Directory reads Q:\mail\Thunderbird\Profiles\32umcxms.default. But that path no longer exists. --- I discovered the file C:\Users\RJD\Application Data\Thunderbird\profiles.ini That is where the "Root Directory" is defined. I can edit that file directly, thereby changing the value Thunderbird displays as Root Directory. (I neglected to mention that I am running Portable Thunderbird. I do not understand why it uses a file in C:\Users\RJD\Application Data\.)

Hello there again
