Changing file extensions

[umzyi]

Hi everyone

Every time I change a file extension of a file, it doesn't update until i restart the system.

For example, if i change the file extensions from quicktime to vlc player, they icon doesn't update but when i click on it, it does open in vlc player but the icon won't update until i restart the system. Same happens while changing from word to pages extension. Is there a way to force update the change of icons or is this a bug?

Any advice on this please? If this is a bug, I'll report to Apple.

Have you tried just restarting the Finder (command option escape to bring up dialog)? That usually fixes such cosmetic problems for me, and it's much faster than a total restart.

tried that already. doesn't change anything unless i restart.

Possibly a Launch Services Database problem. When was the last time you cleaned it out?

Here's an AppleScipt for the purpose:

-- Rebuild Launch Services DB
--BP2013
--Modified from:
-- Adam Bell 2013
-- http://macscripter.net/viewtopic.php?id=40534

say "begin"
set flushLaunchSvcDB to "/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user"
do shell script flushLaunchSvcDB
delay 1
do shell script "killall Finder"
say "done"

Thanks for the script.

I have run the script after changing file extensions and I can confirm that it works. I changes the icons straight away after running the script.

However, I have noticed that you have to run that script every time after changing the file extension.

Does that means that there is actually a bug which is not flushing the services after changing file extensions?

Thanks

That's odd. I only run the script every month or so, when I'm offered 5 different copies of Preview in the "Open With" submenu, yet my icons usually change immediately after I change an extension. You've got somethiong else going on as well, but I don't know what it is. At least you've got a partial fix now.
