By default, imap-backup's configuration is stored as `~/.imap-backup/config.json`. It is a JSON file. You can use a configuration file in another location by passing the `--config PATH` parameter to any command. A typical configuration file looks like this: ```json { "accounts": [ { "username": "my.user@gmail.com", "password": "secret", "local_path": "/path/to/backup/root", "folders": [ {"name": "[Gmail]/All Mail"}, {"name": "my_folder"} ] } ] } ``` # Security Note that email usernames and passwords are held in plain text in the configuration file. The directory ~/.imap-backup, the configuration file and all backup directories have their access permissions set to only allow access by your user. This is not done on Windows - see below. If you choose a custom path for your configuration file, make sure that is not accessible by other users. ## Windows Due to the complexity of managing permissions on Windows, directory and file access permissions are not set explicity. A pull request that implements permissions management on Windows would be welcome!
