Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Directory\shell\sublime] @="Open Folder as &Sublime Project"
[HKEY_CLASSES_ROOT\Directory\shell\sublime\command] @=""C:\Program Files\Sublime Text 3\sublime_text.exe" "%1""
[HKEY_CLASSES_ROOT\Directory\Background\shell\sublime] @="Open Folder as &Sublime Project"
[HKEY_CLASSES_ROOT\Directory\Background\shell\sublime\command] @=""C:\Program Files\Sublime Text 3\sublime_text.exe" "%V""
This file is for Sublime Text 3, To make it ready for other version of Sublime Text just replace "3" with required version.
Thanks.
