Notes about the LPP 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 LPP file type is primarily associated with 'Let's Photo' by Canopus Co., Ltd.. A program that allows you to make DVD animations from your photos. A free trial version will allow you to create but not fine-tune files and saves them to Windows Media files instead of writing to a DVD.
