# Smart Chain Maintenance

# Manually Deleting Blockchain Data

Sometimes it is necessary to manually delete all blockchain data. This should automatically trigger a full re-sync of the Smart Chain.

Users should exercise caution not to delete the wallet.dat file during this procedure. We recommend that the user make frequent backups of the wallet.dat file, especially before deleting files from the data directory.

To erase all synced blockchain data, the following files should be deleted from the .komodo folder:

# Files to Delete

  • blocks
  • chainstate
  • notarisations
  • komodostate
  • komodostate.ind
  • peers.dat

# Default Location for Files

Operating System Directory
MacOS ~/Library/Application Support/Komodo
Windows C:\Users\myusername\AppData\Roaming\Komodo\
GNU/Linux ~/.komodo
