Hello Vishnu,
one way to unpack 7z was as @moenk here wrote, use the Start Process activity with the 7z.exe command line version. Here an example:
Look at the commands and switches of 7z.exe CLI.
It is in no case advisable to use an external activity for Zip/Unzip (not 7Zip), because UiPath offers a build in one, but this support only Zip format, not 7z.
Best regards
