Extract a Single File from a RAR Archive

Demonstrates how to open a RAR archive and extract a single file at a time.

Note: The Chilkat RAR ActiveX objects are included in the "Chilkat Zip" ActiveX download. The RAR functionality contained within ChilkatZip2.dll is freeware, however, the Chilkat Zip, GZip, and .Z functionality is not freeware.

The Chilkat RAR for .NET and C++ are bundled in downloads that contain all Chilkat classes (both free and non-free). Make sure you select the download that matches your .NET Framework or VC++ version (6/7/8).

If running on x64, download the ActiveX, .NET, or C++ builds marked specifically for x64.

#  Note: The Chilkat RAR functionality only provides the ability
#  to open, list, and "unrar" (i.e. extract) RAR archives.  It does
#  not provide the ability to create RAR archives.

#  Also, the Chilkat RAR functionality is free.  It does not
#  require a license to use indefinitely.

    print rar.lastErrorText()
    sys.exit()

#  Alternatively, get an entry by index.  The first entry
#  is at index 0.
