file.getName();

[Java4Life17]

When ever I try to get a File name with file.getName(); it returns nothing.

it does not return the file name. it's for the current section's name.

Use yamlFile.getConfigurationFile().getName() to get the file name, or yamlFile.getFilePath() to get the absolute path.

getName is a method of ConfigurationSection (docs) that returns the name of the configuration section. YamlFile implements ConfigurationSection (is the file's root section), so yamlFile.getName() returns the same as yamlFile.getRoot().getName(), which is blank because root path is blank (yamlFile.getCurrentPath() is blank too, for the same reason).

For instance, yamlFile.getConfigurationSection("test").getName() will return test.
