R01 - WinRAR Split Archive Part 1

What is a R01 file

R01 files are parts of a larger archive file created by either WinRar for Windows or RAR for either Mac or Unix. It's called a split archive file since the R01 can be combined with other split archive files to create a complete compressed file. The bigger archive file is thus "split" into smaller parts. These files are used to compress very large files and save disk space in the process by splitting the huge file into smaller parts.

The 01-part of the file name hints that this split archive is part number 1. In general, WinRAR split archive files have names that follow the pattern "Rnn" where nn stands for a number. They can range from R00 up to R99 for very large archives.

Here's a small, but not exhaustive list of programs that can open R01 documents:

  • 7-Zip (Windows)
  • Corel WinZip (Windows)
  • Incredible Bee Archiver (Mac)
  • RARLAB RAR (Mac & Linux)
  • WinRAR (Windows)
