Service for Windows
ThumbnailCNC is a service that is installed on a computer running Microsoft Windows Vista or newer operating
system. After installation, all the CNC programs (G-code files) on your computer will be represented by a thumbnail
(small picture) when browsing directories with Windows Explorer (Just as you see thumbnails of your
pictures and videos stored on your computer).
Preview
The service also includes a view for the Windows File Explorer preview feature. This view shows both
the actual CNC program (G-code) as text and an image representation of the program's tool paths. Different
versions of Windows have the setting to display Preview in different locations. In Windows 10, click view tab in the File Explorer, then Preview pane.
