How to check thunderbird mail firle location

To check the file location of your Thunderbird mail files, you can follow these steps:

Method 1: Using Thunderbird's Options

  1. Open Thunderbird and go to Tools > Options.
  2. In the Options window, click on Advanced.
  3. In the Advanced window, click on Config Editor.
  4. In the Config Editor window, search for the following settings:
    • mail.server.default.imap.servername
    • mail.server.default.pop3.servername
    • mail.server.default.smtp.servername
  5. Note down the values of these settings. They will be in the format of imap://localhost:143 or smtp://localhost:25. The localhost part indicates the file location of your mail files.

Method 2: Using the Thunderbird Profile Manager

  1. Open Thunderbird and go to Help > Troubleshooting Information.
  2. In the Troubleshooting Information window, click on Open Containing Folder.
  3. This will open the folder that contains your Thunderbird profile. The default location is usually C:\Users\<YourUsername>\AppData\Roaming\Thunderbird\Profiles\<ProfileName> on Windows or ~/Library/Application Support/Thunderbird/Profiles/<ProfileName> on macOS.
  4. Inside this folder, you'll find a subfolder named Mail or Localstore.rdf. This is where your mail files are stored.

Method 3: Using the Windows Explorer (or macOS Finder)

  1. Press the Windows key + R to open the Run dialog box.
  2. Type %appdata%\Thunderbird\Profiles\<ProfileName>\Mail and press Enter. Replace <ProfileName> with the actual name of your Thunderbird profile.
  3. This will open the folder that contains your mail files.

Alternatively, you can use the macOS Finder to navigate to the following location: ~/Library/Application Support/Thunderbird/Profiles/<ProfileName>/Mail

Note: The <ProfileName> part is the name of your Thunderbird profile, which is usually a random string of characters. If you're not sure what your profile name is, you can check the prefs.js file in the profile folder for the user_pref("mail.server.default.imap.servername",...) line, which will contain the profile name.
