Aditional info for windows users, to make ST3
as the default editor after migration.
If you keep both versions or if you uninstall ST2
... probably you will notice that you can't open files or associate open with
by default with ST3
.
I think I can help you get Open With/default editor working.
The problem is that the Sublime Text uninstaller doesn't remove a particular registry entry referring to Sublime Text 2's sublime_text.exe, which prevents Windows from adding an entry for Sublime Text 3's sublime_text.exe.
To 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.
