Similar to the way Notepad++ adds "Edit with Notepad++" to the context menu of all files, or how most Antivirus products will add a global "Scan this file" option, I would like to add a particular program to the context menu for all file types.

Thanks to DOSBox, I'm a little familiar with manually creating file associations and creating context menu options for specific file types.

However, I've got one program I'd like to add as a context menu globally because it can be used with files that have almost any extension. What registry keys do I need to modify for this, and what common pitfalls should I avoid in order to not break things here?

I'd rather do this manually, so that I'm intimately familiar with what changes I'm making to the system, rather than use a third-party tool. The OS I'm doing this on is Windows 7 x64, but it would be great if the same method could be used all the way back to XP. I can probably figure out the necessary command syntax myself - I just need to know which keys to go after and how to format the commands and labels to be properly recognized in those keys.

Here is how you do it with an executable, I would assume it could be done with any program.

Open regedit.exe through the start menu search or run box, and then browse down to the following key:

HKEY_CLASSES_ROOT\ *\shell

Right-click on “shell” and choose to create a new key, calling it “Open with (your program name)”. Create a new key below that one called “command”. Double-click on the (Default) value in the right-hand pane and enter in the following:

"C:\Folder path where the program resides\Program.exe" "%1"

The change should take effect immediately… just right-click on any file and you’ll see the next menu entry.

  • Why am I not surprised to see a HTG article about this? Thanks for pointing me to it. What about the other part of my question - any common pitfalls to avoid, in terms of syntax or other things that could break this?

  • You assume I am smart enough to answer that, thanks. Its a pretty simple and strait forward reg hack, i don't forsee any problems.

  • One thing I am not sure of, if your program executable needs to reside in the system32 folder or not, maybe someone else knows. You might have to change the default data to reflect the file path to your program exe installed, instead of %1. C:\Program Files\My Program\program.exe, someone else needs to chime in here.

  • I'm going on the assumption that it can be wherever you want, as long as you specify the full path (I'll let you know if that doesn't work). For bonus points (and I'll add this to the question): How do I give the action its own icon?

    Indeed, the path does not matter as long as the user has access to it.

You can also try with this little freeware program:

http://defaultprogramseditor.com/

It just sorted out all the mess for me with .js files. Before that I tried several different ways of adding default handler programs. Highly recommended.

Note that I've got nothing with the developer/publisher of the software. Just a happy new user.

Edit: Oh, just found it's been recommended already: Why can't change the default program to open an extension in Windows 7?

There are lots of freeware to do it. My favorite is ContextEdit (freeware, no ads). Other programs can be found at: http://www.thewindowsclub.com/remove-click-context-menu-items-editors

You can also do it with this little freeware program:

 Easy Context Menu
 https://www.sordum.org/7615/easy-context-menu-v1-6/

For example, to add the option to right-click a file in Windows Explorer and edit it using the EditPlus editor, follow the instructions to "Add any program to your context menu" (in the category "File Context Menu"), and add a parameter like the following:

%ProgramFiles%\EditPlus\editplus.exe %1
