Open folders and files with Sublime Text 3 from windows explorer context menu (tested in Windows 10)

OpenWithSublimeText.bat

@echo off
SET st3Path=C:\Program Files\Sublime Text 3\sublime_text.exe

rem add it for folders
@reg add "HKEY_CLASSES_ROOT\Directory\shell\Open with Sublime Text"         /t REG_SZ /v "" /d "Open with Sublime Text"   /f
@reg add "HKEY_CLASSES_ROOT\Directory\shell\Open with Sublime Text"         /t REG_EXPAND_SZ /v "Icon" /d "%st3Path%,0" /f
@reg add "HKEY_CLASSES_ROOT\Directory\shell\Open with Sublime Text\command" /t REG_SZ /v "" /d "%st3Path% \"%%1\"" /f
pause

OpenWithSublimeText3.bat

@echo off
SET st3Path=C:\Program Files\Sublime Text 3\sublime_text.exe

rem add it for all file types
@reg add "HKEY_CLASSES_ROOT\*\shell\Open with Sublime Text 3"         /t REG_SZ /v "" /d "Open with Sublime Text 3" /f
@reg add "HKEY_CLASSES_ROOT\*\shell\Open with Sublime Text 3"         /t REG_EXPAND_SZ /v "Icon" /d "%st3Path%,0" /f
@reg add "HKEY_CLASSES_ROOT\*\shell\Open with Sublime Text 3\command" /t REG_SZ /v "" /d "%st3Path% \"%%1\"" /f

rem add it for folders
@reg add "HKEY_CLASSES_ROOT\Directory\shell\Open with Sublime Text 3"         /t REG_SZ /v "" /d "Open with Sublime Text 3" /f
@reg add "HKEY_CLASSES_ROOT\Directory\shell\Open with Sublime Text 3"         /t REG_EXPAND_SZ /v "Icon" /d "%st3Path%,0" /f
@reg add "HKEY_CLASSES_ROOT\Directory\shell\Open with Sublime Text 3\command" /t REG_SZ /v "" /d "%st3Path% \"%%1\"" /f

rem add it for current folder
@reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Directory\Background\shell\Open with Sublime Text 3"         /t REG_SZ /v "" /d "Open with Sublime Text 3" /f

This is awesome, thank you (Y) (Windows 10 x86)

i don't fully understand. where do i paste this ??

It's a .bat file so just copy-paste to a text file and save as something.bat (then right-click run as administrator). Or download zip using the link.

How to delete it from the context menu plz?

@belive2be You can do so by replacing add with delete in the file and then run it again.

@ahmedhamdy90 cannot delete it by replacing add with delete,
Hint: Error: Invalid syntax

@llan-ml
You can do it manually on regedit.

Or change relevant lines to:

rem delete it for all file types
@reg delete "HKEY_CLASSES_ROOT\*\shell\Open with Sublime Text 3" /f

rem delete it for folders
@reg delete "HKEY_CLASSES_ROOT\Directory\shell\Open with Sublime Text 3" /f

You get an invalid syntax error since options /d, /t , etc. don't exist for reg delete

For reference:

C:\Users\P450>reg delete /?

REG DELETE KeyName [/v ValueName | /ve | /va] [/f] [/reg:32 | /reg:64]

C:\Users\P450>reg add /?

REG ADD KeyName [/v ValueName | /ve] [/t Type] [/s Separator] [/d Data] [/f]
        [/reg:32 | /reg:64]
