Open context menu on file with desired extension in Explorer, than select Open with->You editor ( may be you need to browse for its binary before it appears in the list of available programs ) and set checkbox "Always use the selected program to open this kind of file".
Actually it is not my answer, I have just googled it:
Open regedit (Win+R, type "regedit", select OK).
Navigate to HKEY_CLASSES_ROOT\Applications\sublime_text.exe\shell\open\command
Verify that the path is accurate, correct it if it is not. Exit regedit.
Open task manager via Ctrl+Alt+Del (or Ctrl+Shift+Esc for later versions of Windows), kill explorer.exe, go to run (Win+R) and type "explorer.exe" (or skip this step and simply reboot).
Now attempt the same thing, right click a text file, open with, navigate to sublime, and it should now appear in the list of available applications.
For me that value pointed to the Desktop where portable version previously was placed. Thus it just didn't work.
P.S. And for me the reboot or logout were not necessary (WinXP).
If you are using the portable version, you can't set Sublime as the default program for any files because Windows won't acknowledge it as a program that can open things.
Here are some ways to associate Sublime Text Portable. The following text needs to be saved as a file with a .reg extension and then on that file Right Click > Merge.
This will add a Sublime right click menu entry to all files:
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\*\shell]
@="Sublime"
[HKEY_CLASSES_ROOT\*\shell\Sublime]
@="&Sublime"
[HKEY_CLASSES_ROOT\*\shell\Sublime\command]
@="\"D:\\PortableApps\\SublimeText\\sublime_text.exe\" \"%1\""
This will have Sublime Text replace all calls to notepad.exe:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\Notepad.exe]
"Debugger"="\"D:\\PortableApps\\SublimeText\\sublime_text.exe\" -z"
This will create a SublimeFile class which you can then associate with any extension.
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\SublimeFile\shell]
@="edit"
[HKEY_CLASSES_ROOT\SublimeFile\DefaultIcon]
@="\"D:\\PortableApps\\SublimeText\\sublime_text.exe\",0"
[HKEY_CLASSES_ROOT\SublimeFile\shell\edit\command]
@="\"D:\\PortableApps\\SublimeText\\sublime_text.exe\" \"%1\""
This will then associate the .ext extension with SublimeFile:
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\.ext]
@="SublimeFile"
You can just run CCleaner's registry cleaner tool and then choose and add the default program as usual. It worked for me when upgrading from ST2 to ST3.
@echo off
SET st2Path=C:\Program Files\Sublime Text 2\sublime_text.exe
rem add it for all file types
@reg add "HKEY_CLASSES_ROOT\*\shell\Open with Sublime Text 2" /t REG_SZ /v "" /d "Open with Sublime Text 2" /f
@reg add "HKEY_CLASSES_ROOT\*\shell\Open with Sublime Text 2" /t REG_EXPAND_SZ /v "Icon" /d "%st2Path%,0" /f
@reg add "HKEY_CLASSES_ROOT\*\shell\Open with Sublime Text 2\command" /t REG_SZ /v "" /d "%st2Path% \"%%1\"" /f
rem add it for folders
@reg add "HKEY_CLASSES_ROOT\Folder\shell\Open with Sublime Text 2" /t REG_SZ /v "" /d "Open with Sublime Text 2" /f
@reg add "HKEY_CLASSES_ROOT\Folder\shell\Open with Sublime Text 2" /t REG_EXPAND_SZ /v "Icon" /d "%st2Path%,0" /f
@reg add "HKEY_CLASSES_ROOT\Folder\shell\Open with Sublime Text 2\command" /t REG_SZ /v "" /d "%st2Path% \"%%1\"" /f
pause
I tested this for SublimeText 3(Portable) also and working fine. Create a .bat file with the above code and run it as administrator.
I was facing the same problem.
the only solution was correct it manually
--> open regedit and navigate to Computer\HKEY_CLASSES_ROOT\Applications\, find the sublime_text.exe entry, and delete it. You should now be able to set Sublime Text 3 as the default editor for anything you want.
I tried all options to make sublime text 3 as the default program for my .php, .css and/or .js files
I don't exactly know why it all failed, I think it is related to windows 10 current version bug
But the good news is there is some working way for me, also for those who love CMD
open CMD as administrator
run this line: FTYPE sublime="C:\Program Files\Sublime Text 3\sublime_text.exe" "%1"
for .php files use this command: ASSOC .php=sublime for js use this: ASSOC .js=sublime and so on...
sublime can be set as the default text editor by following these steps:
right-click on the .txt file and select properties.
then in Open with: option click on Change.
if the sublime is listed in the list of apps then select it, if not scroll down and click on the look for another app on this PC and select the sublime app file
