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

OpenWithSublimeText3.bat

@echo off
SET st3_path=C:\Program Files\Sublime Text 3\sublime_text.exe
SET st3_label=Open with SublimeText3 !

rem add it for all file types
@reg add "HKEY_CLASSES_ROOT\*\shell\Open with Sublime Text 3"         /t REG_SZ /v "" /d "%st3_label%" /f
@reg add "HKEY_CLASSES_ROOT\*\shell\Open with Sublime Text 3"         /t REG_EXPAND_SZ /v "Icon" /d "%st3_path%,0" /f
@reg add "HKEY_CLASSES_ROOT\*\shell\Open with Sublime Text 3\command" /t REG_SZ /v "" /d "%st3_path% \"%%1\"" /f

rem add it for folders
@reg add "HKEY_CLASSES_ROOT\Folder\shell\Open with Sublime Text 3"         /t REG_SZ /v "" /d "%st3_label%"   /f
@reg add "HKEY_CLASSES_ROOT\Folder\shell\Open with Sublime Text 3"         /t REG_EXPAND_SZ /v "Icon" /d "%st3_path%,0" /f
@reg add "HKEY_CLASSES_ROOT\Folder\shell\Open with Sublime Text 3\command" /t REG_SZ /v "" /d "%st3_path% \"%%1\"" /f

rem add it for current folder
@reg add "HKEY_CLASSES_ROOT\Directory\Background\shell\Open with Sublime Text 3"         /t REG_SZ /v "" /d "%st3_label%" /f
@reg add "HKEY_CLASSES_ROOT\Directory\Background\shell\Open with Sublime Text 3"         /t REG_EXPAND_SZ /v "Icon" /d "%st3_path%,0" /f
@reg add "HKEY_CLASSES_ROOT\Directory\Background\shell\Open with Sublime Text 3\command" /t REG_SZ /v "" /d "%st3_path% \"%%v\"" /f

It seems like the subl3 CLI has not an option to disable that option.

The better option that I can imagine right now is something like in the .bat above, change st3_path var to point to other .bat executable or something where you modify the sublime config using sed or awk (Right now I’m on Mac so can test this) before open it and setup again after open it.

The idea:

1. Set this settings to false:
   "remember_open_files": false,
   "hot_exit": false,
2. Open sublime:
   "C:\Program Files\Sublime Text 3\sublime_text.exe"
3. Reset to previous settings to the next time that you open without right click:
   "remember_open_files": true,
   "hot_exit": true,

Let me know if this helps,
Regards!
