我重新裝過 thunderbird，之後，在 local folder path 中轉了之前使用中的 local folder，但重新開 thunderbird 後，只餘下幾個 subfolder，而那幾個 subfolder 也是空的，沒有信件。我看過那個 folder size，也有幾十GB，所以信件應該仍在的，可能是 index file 有問題，我曾在 thunderbird 內使用過 repair folder，但沒有反應，好像甚麼也沒有進行過一般。

請問，現在我有何方法可以取回 email 呢？

Thunderbird 9.01
Windows XP x64

謝謝

偶然路過。不知道問題解決了沒。英文知識庫已有說明。你的問題應該要看 "Restoring to a different location" 的部份，共八個步驟。用「Mozilla Thunderbird (Safe Mode)」可啟動 profile manager。

Title: Profiles | How to | Thunderbird
Text: Restoring a profile backup

1. Shut down Thunderbird.
2. If your existing profile folder and profile backup folder have the same name, simply replace the existing profile folder with the profile backup, then start Thunderbird.
Important: The profile folder names must match exactly for this to work, including the random string of 8 characters. If the names do not match or if you are restoring a backup to a different location, follow the steps below.

Restoring to a different location

If the profile folder names do not match or if you want to move or restore a profile to a different location, do the following:

1. Completely close Thunderbird, as explained above.
2. Use the Thunderbird Profile Manager to create a new profile in your desired location, then exit the Profile Manager.
Note: If you just installed Thunderbird on a new computer, you can use the default profile that is automatically created when you first run Thunderbird, instead of creating a new profile.
3. Locate the backed up profile folder on your hard drive or backup medium (e.g., your USB-stick).
4. Open the profile folder backup (e.g., the xxxxxxxx.default backup).
5. Copy the entire contents of the profile folder backup, such as the mimeTypes.rdf file, prefs.js file, bookmarkbackups folder, etc.
6. Locate and open the new profile folder as explained above and then close Thunderbird (if open).
7. Paste the contents of the backed up profile folder into the new profile folder, overwriting existing files of the same name.
8. Start Thunderbird.
