I read that if I need to add item to the context menu for specific files type, I should do the following :
in HKEY_CLASSES_ROOT at Regedit go to the file type you want to modify ((ex:.jpg)) and add "Shell" key if not exists, then create inside the "Shell" key the command you need and inside it create "command" key then in the default value for the "command" key set the application or the command that you want..
This worked perfectly for me for the "non famous" extensions, but when I tried to do that for the ".JPG" file type it didn't worked!
And above all, when I removed the whole ".jpg" key it kept working fine like nothing happened.
My question, should I do something special when I work with this file type or something like this...
Thanks in advance
