Applescript rename files

Your problem is probably in that you're not telling the Finder to do what you need done, as a result, Applescript's own file management dictionary is being used, which cannot rename files. This works, though it could be trimmed significantly:

Code:

tell application "Finder"
	set fileAlias to (choose file)
	set filePath to fileAlias as text
	set TID to AppleScript's text item delimiters
	set AppleScript's text item delimiters to ":"
	set fileName to last text item of filePath
	set AppleScript's text item delimiters to "."
	set fileNamePart1 to text item 1 of fileName
	set fileNamePart2 to text item 2 of fileName
	set fileName to fileNamePart1 & "001" & "." & fileNamePart2
	set AppleScript's text item delimiters to TID
	set name of fileAlias to fileName
end tell

Last line also works as:

Code:

	set properties of fileAlias to {name:fileName}
