Notes about the XCD 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 XCD file type is primarily associated with 'WarpIN'. WarpIN is a general-purpose installer for OS/2. It is available under the GNU General Public Licence (GPL). WarpIN is an OS/2 Netlabs project started in a joint development effort by Jens Bäckman and Ulrich Möller. Now, most development work and maintenance is done by Paul Ratcliffe. This is an XML-like text file.
