This function is implemented to show an error screen when errors occur internally, whether or not such errors are fatal. Control does not return from the function in this case. Use nn::fs::TryCreateFile on everything other than ROM archives.
To read details about error handling, see Handling Errors During File and Directory Operations.
nn::fs::ResultVerificationFailed. However, if this function is called for save data or expanded save data, then the first 512 bytes (or the entire file if the size is 512 bytes or smaller) are guaranteed to be zero-initialized. By using this and writing to the file in the order (Create file > Write data and flush > Write file signature to front and flush), you can check that the file signature has been loaded correctly and guarantee that the file is written correctly.
