Multibit Classic and Multibit HD were two popular wallet software during the 2010s, but they were abandoned in 2017. During that time, many people bought Bitcoins, used Multibit to store them and forgot about them… until recently, when they realized that Bitcoin was worth a lot of money. Now, they would like to access their Bitcoins, but they are not sure where the wallet files are on their computer. How do you find them?
If you are wondering where your Multibit wallet is hiding, the best way to find it is to scan your computer with an application called Treasure Hunter.
How to automatically scan your computer for Multibit wallets
The most reliable way to find a Multibit wallet file is to use software built for this job. This is why I have created Treasure Hunter: instead of going through each file and folder by hand, you simply tell it which drive or folder to scan and it does the work for you.
Treasure Hunter inspects the contents of every file on your computer to determine whether it is a Multibit wallet, so it can recognize your wallet even if it was renamed or moved somewhere inconspicuous. It can also scan removable storage devices such as USB keys. Once it is done, it will let you know if any Multibit wallet files have been detected.
Treasure Hunter works on Windows, Mac and Linux, and it is free.
The manual way
If you would rather not download any software, you can look for the wallet files yourself. Multibit wallets have
filenames that end with .key, .wallet, or .wallet.aes. They are normally stored in the folders below.
On Windows, you should look for the following folders:
C:\Users\<username>\AppData\Roaming\MultiBitC:\Documents and Settings\<username>\Application Data\MultiBitC:\Users\<username>\AppData\Roaming\MultiBitHDC:\Documents and Settings\<username>\Application Data\MultiBitHD
On Mac, you should look for the following folders:
/Users/<username>/Library/Application Support/MultiBit/Users/<username>/Library/Application Support/MultiBitHD
If you cannot find any of the folders above, or if they don’t contain any wallet files, you can instead use your
operating system’s search function and search for files whose name ends with .key, .wallet or .wallet.aes. Be
sure to check any other storage devices you may have used, including external or backup drives.
What to do if you find a Multibit wallet file
Before you do anything else, make a copy of the wallet file and store it somewhere safe. Never experiment with the original file, as it may be silently upgraded, re-encrypted or overwritten by the wallet software. A single botched attempt can destroy the file for good.
Once you have your copy, you can open it with Multibit. If you don’t have a working copy of the software, you can download it by clicking this link.
