How do I get files with no extension to open with Sublime Text 2 by default?

Question

Whenever I download programs or MediaWiki extensions there nearly always are README, INSTALL and COPYING files contained within the downloaded directory(s). These files usually have no file extension and hence the Open With... window has a blocked out

Always use the selected program to open this kind of file

box (hence one can't tick it to say yes to this option). Is there any way around this to get these types of files with no extension to automatically (i.e., by default) open with Sublime Text 2?

Answer 1

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.]

[HKEY_CLASSES_ROOT\.\shell]

[HKEY_CLASSES_ROOT\.\shell\open]
@="Open &with Sublime Text"

[HKEY_CLASSES_ROOT\.\shell\open\command]
@="C:\\Program Files\\Sublime Text\\Sublime.exe \"%1\""

Modify the path to the Sublime Text executable as required, save as a .REG file and double-click to import into the registry.

Answer 2

Go to registry editor and add extension . (only dot, nothing else, check .txt as reference example) to the extension rules. Check any other relevant extension to see the correct name tags for the open fields. You can even add the entry OpenWithList and add multiple handlers there.

Practically, it should look something like:

[HKEY_CURRENT_USER\Software\Classes\no.ext\shell\open\command]
@="c:\pathtoapp.exe \"%1\""
[HKEY_CURRENT_USER\Software\Classes\.]
@="no.ext"
