Lets say you have used the Mozilla Thunderbird client for some time and have decided to move to the cloud, more precisely to Gmail or Google Mail. Question is, how do you get your emails and the folder structure over to Gmail? Sure you could do that manually; Create the folders over at Gmail and forward each and every of your emails to your Google email address. But that's not very practicable if the mail count exceeds a few dozen. What if you have thousands of emails neatly sorted in folders?
You need a third party software like Google webMail Filer for Thunderbird then. The free open source application can process Thunderbird mbox (mailbox) files and import them into Gmail.
Users need to supply their gmail username and password so that the application can import the mails into the account. That's a problem for some. The source code is provided on the developer page which means that it is possible to review the code before the software is used.
I'd still recommend to change the password as soon as the operation has completed successfully. The mail export itself is very simple. It begins by entering the Gmail username and password into the required fields before loading a Thunderbird mail folder using the built-in file browser.
The program scans the selected folder and displays all mbox files in a listing. Each can be selected individually or all by selecting the Tootle Selection option. A click on start filing starts the export of the mails to Gmail. The program monitors the size of the Gmail inbox to block uploading once an 85% fill rate is reached.
Users interested in the portable software can download it and its source from the developer homepage over at Admincraft. The software is compatible with 32-bit and 64-bit editions of Windows and requires the Microsoft .NET Framework 3.5.
