Hi Bob Openshaw,

The trace image "lives" in your computer and it is not part of the Punch file. For example, if you open the file in other computer and you try to visualize the trace image, you will receive a message stating that the image is not available
In other words, Punch only shows the image, the memory is not used in this process
Anyway, if you wish to delete the trace image, try this
1 - In your Punch program--> make the trace image "not visible"--> close your Punch program
2 - Go to your Windows Explorer--> Go to the location where your image is stored--> move the image to (any) other location
3 - Open Punch--> Open your file--> Make the trace image visible--> Your will receive a message stating that the image is not available and if you wish to set other trace image--> answer "No"--> the original trace image will be deleted
