OS X 10.7 Lion Finder - Folders on top

gistfile1.txt

Open Terminal.
Type this command:

cd /System/Library/CoreServices/Finder.app/Contents/Resources/English.lproj/
Now, the file we want to mess around is the InfoPlist.strings. But unfortunately, this file cannot be edited directly using text editor in Lion. But no worries. Run this command to make it editable.

sudo plutil -convert xml1 InfoPlist.strings
Now the file should be editable and readable. Use your favorite text editor and open InfoPlist.strings. I just used vim

sudo vim InfoPlist.strings
Inside you’ll find XML document. Go to the following lines:

<key>Folder</key>
<string>Folder</string>
All you have to do is to add a space before the second Folder like this:

<key>Folder</key>
<string> Folder</string>
Save the file. Convert the file to binary again using the following command.

sudo plutil -convert binary1 InfoPlist.strings
Restart Finder.

killall Finder
That’s it!
