Changing Finder's Font Size - Lion I open My Documents in finder.  Click CMD-J and change the font size to 10.  I choose set as default.  The font size looks right on My Documents.

Then I navigate to Applications, and the font size is 12.

Is there a way I can change my font size on all folders?

Thanks!
You have to delete the .DS_Store files in each folder.


How to do that? Via Onyx. You can also unhide all invisible files (.DS_Store files are invisible) and delete them one by one. 

After that, you can "set default" in the root folder and it should be in all the folders below 


  / -> /Applications 
        / -> /Documents etc.
