How add context menu item to Windows Explorer for folders [closed]

Question

In the registration editor (regedit.exe) find:

• Context menu for right click on folders in left panel of Windows Explorer or on background of a directory in right panel:

1. HKEY_CLASSES_ROOT\Directory\Background\shell if you are administrator
2. HKEY_CURRENT_USER\Software\Classes\directory\Background\shell if you are a normal user

• Context menu for right click on folders in right panel of Windows Explorer:

1. HKEY_CLASSES_ROOT\Directory\shell if you are administrator
2. HKEY_CURRENT_USER\Software\Classes\directory\shell if you are a normal user

• Context menu for any file:

1. HKEY_CLASSES_ROOT\*\shell if you are administrator
2. HKEY_CURRENT_USER\Software\Classes\*\shell if you are a normal user

In all cases:

1. add a new key under shell, naming it as you want to name the context menu item
2. add a new key inside this key, named command (mandatory name)
3. edit the default property in command to myprogrampath\path\path\executable.exe "%1" to pass the file path and name of the selected file to your custom program (for .../Directory/Background and .../directory/Background cases use %V instead of %1)

More customization:

• Add icon: add a string value named icon for key created at step 1 with value matching an icon resource path. You can also provide an integer arguments to specify which icon to use. Example: %SystemRoot%\System32\shell32.dll,3
• Display only on shift-click: add an empty string value named Extended for key created at step 1
• Customize menu entry label: change the value of default value for key created at step 1
• Change menu entry location: add a string value named Position with one of: Top, Bottom

Found a cleaner, easier and faster solution: create a text file, fill it with these contents, update it to your needs, save with .reg suffix and launch it (it does not need administrator priviliges because it accesses user-part of the registry):

Windows Registry Editor Version 5.00

; Setup context menu item for click on right panel:
[HKEY_CURRENT_USER\Software\Classes\directory\Background\shell\MenuItemNameBackground\command]
@="C:\\yourpath\\executable.exe \"%1\""

; Optional: specify an icon for the item:   
; HKEY_CURRENT_USER\Software\Classes\directory\Background\shell\MenuItemNameBackground]
;"icon"="C:\\yourpath\\appicon.ico"

; Optional: specify a position in the menu
; HKEY_CURRENT_USER\Software\Classes\directory\Background\shell\MenuItemNameBackground]
;"position"="Bottom"

; -------------------------------------------------------------------------------------

; Setup context menu item for click on folders tree item:
[HKEY_CURRENT_USER\Software\Classes\directory\shell\MenuItemNamePanel\command]
@="C:\\yourpath\\executable.exe \"%1\""

; Optional: specify an icon for the item:   
; [HKEY_CURRENT_USER\Software\Classes\directory\shell\MenuItemNamePanel]
;"icon"="C:\\yourpath\\appicon.ico"

; Optional: specify a position in the menu
; [HKEY_CURRENT_USER\Software\Classes\directory\shell\MenuItemNamePanel]
;"position"="Top"

In this way you can also have a backup of your configuration: just save the .reg file in a safe place. If you manually edit the registry after launching the file, right-click and slect "export".

Beware of double backspaces in path: \\

I went back and also answered this in another topic since there doesn't appear to be much on this question specifically.

I found the simplest way was to add a String Value to the key called "AppliesTo" and set its value to "under:{path}"

In my example, I want it to only look in the T Drive, so my String value is "AppliesTo":"under:T:".

In C#, this is easily accomplished with the following:

RegistryKey _key = Registry.ClassesRoot.OpenSubKey("Folder\\Shell", true);
RegistryKey newkey = _key.CreateSubKey("My Menu Item");
newkey.SetValue("AppliesTo", "under:T:");

RegistryKey subNewkey = newkey.CreateSubKey("Command");
subNewkey.SetValue("", "C:\\yourApplication.exe");
subNewkey.Close();

newkey.Close();
_key.Close();

The only good solution I found a really working is : https://superuser.com/questions/1097054/shell-context-menu-registry-extension-doesnt-work-when-default-program-is-other

Add keys in HKEY_CLASSES_ROOT\SystemFileAssociations\your.extension\shell\command Modify the last key with the command you wanna do.

For my purpose it was :

"C:\Program Files (x86)\GPSBabel\gpsbabel.exe" -r -i gpx -f "%1" -x simplify,count=1000 -o gpx -F "%1.gpx"

If I export the it I get a .reg :

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\SystemFileAssociations\.gpx\shell\Simplify gpx\command]
@="\"C:\\Program Files (x86)\\GPSBabel\\gpsbabel.exe\" -r -i gpx -f \"%1\" -x simplify,count=1000 -o gpx -F \"%1.gpx\""

Open command prompt [run as administrator] and execute this command

reg add "HKEY_CLASSES_ROOT\Directory\shell\Refi2\command" /d "powershell.exe -noexit -command Set-Location -literalPath '%V'"

• -d : value to execute[app name exe].
• -v : creates a new subkey inside the command key.
• -f : to forcefully override the key if already exists.
• powershell.exe -noexit -command Set-Location -literalPath '%V' instead of this you can specify path of your exe.

reg add /?
