Usually, the program that opens a file type is stored in the following key in the registry (where filetypename
is the name of the file type):
HKEY_CLASSES_ROOT\filetypename\shell\Open\command
But for image files such as PNG or JPG, the only key in the shell
key is printto
, which is the Print command. However, when I right click on the image, there is still an Open command, but it doesn't seem to be anywhere in the registry. Why is this? Can files have commands that aren't in the registry? Or is this command's key somewhere else in the registry?
