How can I find my `chaindata` folder?

  • Someone referred me to the chaindata folder to troubleshoot a problem I am having with Ethereum-Wallet/Mist. How can I find it?

  • geth (used in the Ethereum Wallet) saves its internal states for the main network in the chaindata directory. You can find it in the:

    • ~/.ethereum on Linux
    • ~/Library/Ethereum on OS X
    • ~/AppData/Roaming/Ethereum on Windows

    In these directories, there are:

    • chaindata: production blockchain
    • testnet: test blockchain
    • keystore: your keys

    For OSX there are two library folders. You will need to enable hidden folders to fine the `Library` referenced above which is found in `HD/Users/{your name}/Library` and is a hidden folder

    To view hidden folders run this in terminal `defaults write AppleShowAllFiles YES` then relaunch finder (option+control click finder icon and select relaunch)

    On mac open finder and press Cmd+Shift+G then you can directly navigate to the path `~/Library/Ethereum`

  • When you first launch Ethereum-Wallet it will show the splash screen. Shortly after the splash screen will show a LAUNCH APPLICTION button. Click this button to see the full UI. If you are fully synced already it may skip straight to the full UI

    Once that is open go to the Accounts menu > Backup sub-menu > Accounts menu-item.

    The UI for your file explorer will differ by OS, but you should see a folder that contains folders like this, in particular it should contain a chaindata folder:

    Side-note: While you are here you should backup the keystore folder. Details about this can be found at How do I backup my ether accounts?. Be sure to save your passwords as well!

    We also emphasize that for each file in `keystore`, you also need to backup your **passwords**,

    Edited to link to that question and mention saving password.

    How does this answer relates to the actual question? Surely one of those has been edited, I need to downvote in this case. #offtopic

    The question was how do I find chaindata folder in must. This is a direct answer to that. I'm not sure why you believe it isn't?

  • On Mac OSX or GNU Linux, simply open a terminal and search for your chaindata using the find commandline tool:

    find ~ -type d -name 'chaindata'

    Where the first parameter ~ tells to look into your $HOME directory and all subfolders. Type d is for directories only.

    A possible result looks like that:


    As you can see, I have multiple blockchains on my computer.

  • On an Ubuntu system in a terminal/ CLI you can use:

    locate chaindata
