I am able to unzip all files using below command in SSIS processTask.
Executable: c:\Program Files\PKWARE\PKZIPC\pkzipc.exe
Arguments: -extract -overwrite "C:\MyFolder\xyz.tar.gz" "c:\MyFolder\"
there are multiple file in the zip folder and unzipping process is extracting files in alphabetical(a-z) order but I want to unzip selected files on custom order.
