[`delete_path`](#delete_path) `static` | Delete path (file or directory) | | `Result< size_t >` | [`file_size`](#file_size) `static` | Get file size in bytes. | | `Result< std::vector< std::string > >` | [`list_files`](#list_files) `static` | List files in directory. | | `Result< std::string >` | [`read_file`](#read_file) `static` | Read entire file into string. | | `Result< std::vector< std::string > >` | [`read_lines`](#read_lines) `static` | Read file into vector of lines. | | `Result< void >` | [`write_file`](#write_file) `static` | Write string to file (overwrites existing) | | `Result< void >` | [`append_file`](#append_file) `static` | Append string to file. | | `std::string` | [`get_extension`](#get_extension) `static` | Get file extension (without dot) | | `std::string` | [`get_filename`](#get_filename) `static` | Get filename without directory. | | `std::string` | [`get_directory`](#get_directory) `static` | Get directory path. | | `Result< std::string >` |
