File Extension R01

The file extension R01 is a file that is commonly known as a WinRAR Split Archive file. WinRAR Split Archives are a compressed file format associated with a variety of RAR compression utility programs. Split Archive files are a collection of files that have been packaged as one large file for the purpose of storage and backup. The files are packaged together as a way of organizing and storing large volumes of data.

The file extension R01 is a compressed file type that represents one in a series of volumes which have been separated for the purpose of storing large volumes of information on multiple storage disks. The volumes typically begin with R00 and end with volume R99. The volume of files was originally created for floppy disks to provide a way to store more data on a disk which did not offer a large amount of storage space.

The process of splitting files was later used to compress files to a CD to enable the transport of data saved to a disk. In order to burn the files to a CD/DVD under the ISO 9660 standard, it was necessary to split the files. In the current day, multi-volume files such as WinRAR Split Archive files are used for P2P file sharing on the Internet and as a method for storage and backup of large volumes of data.
