Is it possible to set by default to show hidden files and folders in Open and Save dialogs ?

I know it is possible to trigger to show hidden for dialog lifetime by press Command ⌘+Shift ⇧+..

I just asked this question again, since there were no real answers here, and according to this answer all you need to do is run

defaults write -g AppleShowAllFiles -bool true

and restart whichever application(s) you're using, and you're all set. No restarting Finder or your computer. Brilliant!

This is not work. – diimdeep Aug 18 '13 at 14:23
It works on Mountain Lion 10.8.4, I don't know about other versions. You may also need to use sudo at the beginning of the command – MattDMo Aug 18 '13 at 23:35
Tried again, it works but not everywhere, it is depends on application.. in TextEdit for example not. – diimdeep Aug 19 '13 at 7:15

Not without using the chflags nohidden command, which is not recommended. One of the third-party file manager utilities such as PathFinder may have such an option.

chflags nohidden work only for Finder, not Open/Save dialogs. Also I don't see how PathFinder can help. – diimdeep Sep 26 '12 at 18:40
chflags nohidden should affect file dialogs as well, but it can't be used to show files that start with a period. – user495470 Sep 27 '12 at 10:48

In the terminal enter

defaults write AppleShowAllFiles 1

This will work only when you browsing through Finder itself, my question is when you browsing through Save or Open dialogs in any other application. – diimdeep Sep 27 '12 at 6:42
@dimdeep MattDMo's answer worked for me – Sean A Aug 3 '14 at 21:52
