Ethereum: Bitcoin/blocks folder up to 17gb [duplicate]

Ethereum: Pruning a Large Bitcoin Blocks Folder

As you may have noticed, the “blocks” folder in your Ethereum installation has grown to a whopping 17GB. This is not unexpected, given that Bitcoin-QT v0.8.6-beta is a relatively large and complex wallet software.

To prune this large folder, we’ll need to identify what’s taking up most of the space. Here are some steps to help you remove unnecessary files:

1. Check for unnecessary files in the “blocks” directory

Open Command Prompt as an administrator (right-click the Start button and select “Command Prompt (Admin)”) and navigate to your Ethereum installation directory:

cd C:\Users\user\AppData\Roaming\Bitcoin\blocks

Use the dir /s command to list all files in the folder, including subdirectories:

dir /s /b

This will display a detailed list of files and subfolders. Look for unnecessary or redundant files that you can safely delete.

2. Delete system files

Some files may be created by your operating system or the Ethereum software as part of its installation process. These are usually harmless, but deleting them won’t do any harm:

dir /s /b > SystemFiles.txt

This will create a text file named SystemFiles.txt in the same directory as your wallet folder.

3. Delete duplicate files

Bitcoin-QT creates multiple copies of its block database in different directories. Deleting these duplicates can help free up space:

dir /s /b > DuplicateBlocks.txt

This will create a text file named DuplicateBlocks.txt in the same directory as your wallet folder.

4. Delete unnecessary Ethereum data

Ethereum uses a separate blockchain database for each Ethereum node. Deleting this database can help free up space:

del C:\Users\user\AppData\Roaming\Bitcoin\eth.json > EthereumDataRemoved.txt

This will create a text file named EthereumDataRemoved.txt in the same directory as your wallet folder.

5. Uninstall Unnecessary Software

If you have installed additional software that contributes to the big blocks folder, uninstalling it may help:

• Open System Properties (Windows) or System Preferences (macOS) and look for Bitcoin-QT related software entries.

• Remove any unnecessary software from these entries.

6. Consider Upgrading to a Newer Version of Ethereum

If you are using an outdated version of Bitcoin-QT, consider upgrading to the latest version, v0.9.4-beta:

bitcoind --upgrade-eth qt 0.9.4-beta

This will update your wallet and possibly reduce the size of the blocks folder.

By following these steps, you should be able to reduce the large blocks folder on your Ethereum installation. Remember to back up all important files before making any changes, as some data may be unrecoverable if accidentally or intentionally deleted.
