Notes about the DTO 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 DTO file type is primarily associated with 'Team Oracle' by Team Oracle. This site appears to be in development. This extension is used by Team Oracle software and games. It can be an audio file, video file, a database file, or any other type of file.
