Ever renamed multiple library items by hand? I know I did. So some good people came up with this absolutely crucial scripts for you Flash:

Meet Library Items Renamer 1.2 (author)
Which let’s you rename multiple library items with an added suffix at the end.

And libAppend (author)
This one let’s you append prefix, suffix or both to your current library items name.

Both scripts come as a .mxp format and installed via Adobe Extension Manager. Both scripts work miraculously on all Flash CS versions.

Happy renaming!
