Sometimes I need to make a backup of all my messages to free up disk space.
I would like Thunderbird to have an integrated tool with the following features:
Archiving entire mail or selected range: I would like to be able to archive all messages or select specific ranges for archiving. The archive should include emails along with their attachments.
Saving the archive to disk: The archive should be saved in a chosen directory on the disk. Additionally, it should be possible to save the archive as an encrypted zip file or in another format that ensures data security.
Proper character encoding: It's important for the tool to support the encoding of Polish and other characters so that all content is stored and read correctly.
Mounting the archive in Thunderbird: It's crucial to be able to directly mount the archive in Thunderbird as a new mailbox labeled as an archive. This way, I would be able to easily access the data, browse the contents, search messages, and check contacts and attachments.
Introducing such a tool to Thunderbird would allow me to easily manage my archived messages and maintain order on my disk.
