Dogecoin Core file system
Contents
Data directory location
The data directory is the default location where the Dogecoin Core files are stored.
- The default data directory paths for supported platforms are:
| Platform | Data directory path |
|---|---|
| Linux | $HOME/.dogecoin/ |
| macOS | $HOME/Library/Application Support/Dogecoin/ |
| Windows | %APPDATA%\Dogecoin\ [1] |
-
A custom data directory path can be specified with the
-datadiroption. -
All content of the data directory, except for the
dogecoin.conffile, is chain-specific. This means the actual data directory paths for non-mainnet cases differ:
| Chain | Data directory path |
|---|---|
| (default) | path_to_datadir/ |
-testnet |
path_to_datadir/testnet3/ |
-regtest |
path_to_datadir/regtest/ |
