File extension 003 information

File extension 003 is the third file of the WinRAR application multi-volume archiving file. WinRAR archive’s native format is RAR. Similar to other archives, RAR files are described as data containers as they store a single or a number of files in their compressed form. In order to use an online downloaded RAR file, the contents need to be unpacked. Some RAR files are at times part of sequences that are multi-volume in nature. Within WinRAR one can split a large archive into a number of smaller files called volumes.
.003 files can have extensions such as .part1.rar (the opening volume), .r01, r00, alternatively, .rar (the opening volume), and so on. If volumes need unpacking, they are placed into matching folders, where extraction from the opening volume begins. WinRAR offers a graphic interface that is interactive and uses menus and mouse as well as command line interface. It is easier to navigate when tested or compared against other archivers due to its inclusion of a wizard mode. This special feature allows on the spot access to basic functions of archiving within it.
