File extension R01 (.R01) information

Appropriate program:

The .R01 file extension identifies a split WinRAR compressed archive file. When archiving and compressing a file WinRAR may choose to split it into separate smaller units, each of which will be given a different file extension from the range .R00 through to .R99, as required.. Incorrect associations are the cause of many file extension errors. Scan your system to prevent and identify association errors.
