How to retrieve ascx file from WSP in SharePoint2013


How to retrieve ascx file from the Template folder in SharePoint2013

My issue is, I have WSP only so I changed into zip and got my all web parts and also one dll file after that decrypted dll and got some C# code mixing with some system generated code but not ascx file that is for front-end part. So how we can retrieve full flash solution if not, at least ascx files So if we were on SharePoint 2010 we could have got those file from Template folder but It’s on SharePoint 2013 and not able to get ascx.

If we can do so, than will be easy to get the task to be done

Suggestions would highly be appreciated. Thanks in Advance.
