Notes about the U3P 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 U3P file type is primarily associated with 'U3 Platform' by U3 LLC.. The U3 platform enables hardware manufacturers and software developers to create U3 smart products. U3-compatible flash media will be able to carry and run applications directly from the flash media to allow a user to carry a completely portable device for secure use on any computer with a USB port. Many programs will use this extension to create install packages for installation on U3-compatible devices.
