I have used Thunderbird for years. I kept the original profile for archiving. Since you can't have more than one primary structure, each year, I create a feed named by the archive; for example, Mail 2024 would contain last years emails. The current profile has been emptied. In the past, I could use the profile manager to look at yearly emails in the original profile. Something has change, now I can set the feed names but I can't access the mail files. I checked and the files are there but they are not accessible via Thunderbird. See Attachment. Can I delete the diskspace files or rebuild them? Thanks, Sandi
