AppleScript to Make Filenames Unique

I needed this when I import photos from several sources and they have overlapping names. Simply select all the files and execute this script, probably from the User Scripts Folder.

Step 1: Add the AppleScript Icon to the OSX Menu Bar

Inside the AppleScript editor (in your OSX Applications - Utilities) go to Preferences - General and check

[x] Show Script menu in menu bar

Step 2: Add This Script to Your User Scripts

# AppleScript (multi) rename script for Finder files.
# Hens Zimmerman, October 16, 2011.
 
# Iterate through all files and rename them.
 
tell application "Finder"
    set filenames to selection
    set theCount to number of items in filenames
     
    repeat with idx from 1 to theCount
        set theFile to (item idx of filenames as text)
        set TheName to name of (theFile as alias)
        set UUID to do shell script "uuidgen"
        set NewName to (UUID & " " & TheName)
        set name of file theFile to NewName
    end repeat
end tell

Step 3:

Now in the OSX Finder, simply select the files you want to give a unique filename and execute the script.
