.R01 File

The r01 file extension is associated with WinRAR. Its one part of a multi-volume compressed RAR archive.

The rar file extension is used for the native format of WinRAR archiver. Like other archives, rar files are data containers, they store one or several files in the compressed form. Compressed archives are common on internet, especially on sharing sites.

After you have downloaded rar file from Internet, you need to unpack its contents in order to use it. Comparing to ZIP file format, RAR provides a number of advanced features: more convenient multipart (multivolume) archives, tight compression including special solid, multimedia and text modes, strong AES-128 encryption, recovery records helping to repair an archive even in case of physical data damage, Unicode support to process non-English file names and a lot more.

Some *.rar files can be parts of a multi-volume sequences. In WinRAR you can split a huge archive to a few smaller files, which are called volumes.

Older versions of WinRAR used either:

• .rar or exe (SFX) for first volume
• .r01, r02, r03 .... etc. for any additional volumes

Or:

• .rar or exe (SFX) for first volume
• 001, 002, 003 .... etc. for any additional volumes

The newer versions of WinRAR are using:

• .rar or exe (SFX) .... etc. for first volume
• part1.rar, part2.rar, part3.rar for any additional volumes

In order to unpack the multi-volume RAR archive, you need to place ALL of the split parts in the same directory and start extraction of the first volume. The program will automatically use all of the parts to extract the content of the archive.

An r01 file extension is traditionally used for older RAR split multi volume archives. A single archive split to many pieces so they could be more easily downloaded / transferred. In the days of floppy disks, this was a pretty common practice. An r01 represents the second part, the first having rar/exe file extension. In order to extract the content of this archive, you first need to put all pieces to single directory and extract the first archive.

How to open:

The r01 file is only one part of RAR multi-volume archive. If you want to extract this file, you must have all parts of the RAR multi-volume archive. Open the first part of RAR multi-volume archive in WinRAR application and extract files from RAR multi-volume archive.

How to convert:

It is not possible to convert only one part of RAR multi-volume archive. Only complete RAR archive can be converted in to another archive or compression format. The easiest way how to convert complete RAR multi-volume archive is to decompress the RAR archive with the use of WinRAR and repack the content with another compression or archive application of your choice.
