Hello,

create an 'execute process task'.

In Process / Executeable insert the execute (...winzip.exe )

In Expressions select the property Arguments. Here you insert

"-a -ex zipfile.zip examplefile".

A better approach is to work with variables for zipfile.zip and examplefile i.e.

"-a -ex " + @[user::zipfile] + " " + @[user::file]
