Notes about the WTP file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The WTP file type is primarily associated with 'Wink' by Satish Kumar. S.. Wink is a Tutorial and Presentation creation software. Using Wink you can capture screenshots, add text boxes, buttons, titles etc. and generate a tutorial.
