Extracting .rar file in NIFI

[#1]

 I am getting .zip files as well as .rar files from my source location. While i am able to unzip the .zip files using unpack content processor , i am not able to extract the .rar files. I even tried compress component processor but seems that too doesn't support .rar files.  How should i extract the .rar files ?  install winrar in root folder and then call it using execute stream processor ?

UnpackContent processor do not support .rar file:

Hence, yes you can use an ExecuteStreamCommand processor to invoke WinRAR command-line tool.
