''<p>e.a1964 [[#question-1464596|đã nói]]</p>'' <blockquote>Hello, I have a Laptop with Windows 11 Home and Thunderbird 128.2.1esr installed. Because my system partition was fully and my Thunderbird data took about 60GB I wanted to move it to a data partition on the same drive (C: -> H:). I found a tutorial that explained to shut down Thunderbird. Move/Copy the profile folder form C:Users\x\AppData\Roaming\Thunderbird\profiles\profile-name.default to the new desired location on H:. Then create a new Thunderbird profile via the profile manager that points to the new location and set it to default. Then turn on Thunderbird and thats it. It did it and it seem to work first. Everything was there after checking in Thunderbird. Then I decided to delete the old profile folder to free space up on C:. When I turned Thunderbird on again some stuff was missing. There are local folders, a gmail account and three email accounts from another provider. The local stuff and gmail look good, everything on its place. But the folders from the other provider are missing completely. Only the inboxes are there. But since they were kept empty always I can't tell if thats correct or a problem. The owner always kept the inbox empty by moving stuff to other folders (inside the account). But they are all not shown since the second start. </blockquote>
