Here's a Script for moving a whole folder of items...
tell application "Finder"
activate
set source_folder to choose folder with prompt "Please choose the Source-Folder:" default location ((path to home folder) as alias)
set source_files to every file in source_folder
set target_folder to choose folder with prompt "Please choose the Taget-Folder:" default location (":Applications:" as alias)
repeat with i from 1 to number of items in source_files
set source_file to (item i of source_files)
move source_file to (target_folder) -- use "copy source_file to folder (target_folder as alias)" to copy the files
end repeat
set question to display dialog " Files have been moved."
end tell
You should be able to modify that for one file.:)
