Mac OS X Leopard Tips and Tricks

Finder

Sort Folders Before Files

This only works when you sort by kind... Just edit with emacs or any other text editor (as root) the file:

System/Library/CoreServices/Finder.app/Contents/Resources/English.lproj/InfoPlist.strings

and change the line:

/* General kind strings */
"Folder" = "Folder";

to:

"Folder" = "~Folder";

Restart OS X.
