Thunderbird is a safe, fast, free-of-charge and easy-to-use cross-platform mail client by Mozilla, very popular with users. The Thunderbird profile accumulates large amounts of data which can be lost after mail client failures, virus attacks or hardware problems, and even after trivial reinstallation of Windows. So what can be done to make sure that you don't lose, or if it did happen, that you can successfully recover your profile data in Mozilla Thunderbird? Thunderbird Profile Files In the profile, Mozilla Thunderbird saves all users' client settings as well as passwords, address books, extensions and electronic message files. Unlike all other mail clients, such as Outlook, Thunderbird does not save all profile information in one file. This is a folder with a particular set of other folders and files that enable the mail client to work and save its data. The Thunderbird profile is created when the application is launched for the first time, and it is saved to this default directory – C, Users, username, AppData, Roaming, Thunderbird, Profiles. In our case, the folder with files has a name like this, which is a randomly generated sequence of symbols. A Thunderbird user profile contains a certain list of files and folders, such as Abook.map and Historymap, the files containing the mail client's address book, search.db, key.db, segmod.db, the files containing certificate databases and certificate key databases, localstore.rdf, the file of window size and location as determined by the user, mailviews.dat, the file dealing with messages viewing modes, panacea.dat, the file containing mail folder cache, which is used to display the tree folder of the mail client, perhaps .js, the main configuration file of Mozilla Thunderbird, and some others. In addition to these files, the profile folder contains a certain set of folders, with two of them being very special. Mail – the folder which is default location for POP3 mail accounts. Files for every account are stored in a separate subdirectory. IMAP Mail – the folder which is a default location for IMAP mail accounts. Files for every account are also stored in a separate subdirectory. These are the two folders that contain all user correspondence inbox and send messages. Each mailbox folder has a separate .msf file assigned to it and having the same name as this folder both in the mail client and in the online mailbox. Mozilla Thunderbird has no built-in tools for creating a backup copy of profile data or user correspondence files. That is why if you need to transfer a user profile to another computer or if your computer or its operating system fails for some reason, there are only two variants. To use third-party software, or create a profile backup manually. To do it, go to the folder containing your Thunderbird user profile. See users username appdata roaming Thunderbird profiles. Please remember that the folder appdata is hidden, and in order to get there, you will have to make hidden files and folders visible in your computer. Open the folder with a profile and save it to a convenient location, for example a DSD or an external hard disk. Now let's go to restoring Thunderbird data from a backup copy. If your computer is out of order, your windows is reinstalled or if you just need to transfer your Thunderbird data to another computer, you can do it by restoring it from a previously created profile backup. To do it, install Mozilla Thunderbird on your computer and start it. Without starting, the application will create a new profile in the default folder, profiles, and you could see the path earlier in this video. Close the application without making any changes to the mail account settings. After that, go to the folder C, users username appdata roaming Thunderbird profiles and replace the contents of the new profile folder with files and folders from the previously created backup copy of your Thunderbird profile. Start Mozilla Thunderbird and all incoming and sent messages, settings and calendar notes will be transferred to the freshly installed mail client. Now the most interesting part – recovering the Thunderbird profile with Hetman Partition Recovery. You formatting the computer's hard disk or installing its operating system resulted in deleting Mozilla Thunderbird profile folder or backup, they can still be recovered with Hetman Partition Recovery. To do it, download, install and launch Hetman Partition Recovery. Use it to scan the disk where you saved the Mozilla Thunderbird profile or the profile backup you have created. Using the program, go to the folder where your profile was saved on this computer. Recover the folder or the Thunderbird profile backup. Recover mail client data from backup as I shown you earlier in this video, that is, replace the Thunderbird profile with the files of the profile that you have recovered. To make the process of recovering Mozilla Thunderbird profile backup much easier, recommend creating an archive with the extension zip or rough, containing a copy of the profile folder. In this case, recovering the profile will only be about recovering a single file, not a folder full of files. In particular, the complicated cases of data loss. The full analysis you will be able to search for it by file name after the data recovery software restores the folder. As I have already said before, all user correspondence is stored as encrypted data in the files having the same names as mailbox folders. Such files are stored in the profile folder in subdirectories named mail and imap mail. All information in such files is encrypted by the mail client. However, the addresses of mailboxes to which messages were sent or from which they were received are not encrypted. That is why if you lose access to your Thunderbird profile for some reason, you can find and recover certain email messages by opening the required file in the Mailbox folder with a text editor. For example, if you need to recover from the folder inbox the email addresses which end in HetmanRecovery.com, you should put HetmanRecovery.com in the text editor search field and it will show all the mail addresses with such ending that it was able to find.
