    Hi all,

    I'm getting this message when trying to open a workflow. It is workflow 7.1 (not sp2). Does anyone know how I can fix this?

     

    Thanks

    It looks like you have an "Extract Files from ZIP" component in your workflow that is trying to process an file that does not have a .ZIP file extension. The "Extract Files from ZIP" component will return that sort of an error when it tries to process a non-ZIP file, like a GZipped file (.gz file extension) for example.
