Notes about the OSD 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 OSD file type is primarily associated with 'Directory Opus' by GPSoftware. Directory Opus goes beyond the simple file manager metaphor, and offers you a complete replacement for Windows Explorer and many other utility programs for handling FTP, ZIP, viewing files and images, running slideshows and more. In Directory Opus 9, all configuration is now stored on disk in XML format (except the file extension is .OSD).
