fla2img

Retrieves all the image files within your .fla files.

How to use it

You can either run it thru cli:

Passing a single file

sh fla2img.sh foo.fla

Passing multiple files

sh fla2img.sh foo.fla bar.fla

Passing a path of files

Or simply open the .fla files with the images you want, then drag fla2img.jsfl to Flash icon.

It's recommended to close your current documents before executing this script.
Fully tested with a bunch of files at once. It performs well.
Don't worry about internal collisions between library items. This script is able to take care of it.
After processing, the script will print you an overall report of files exported among other stats.

It works by creating an empty document which will handle every single opened .fla, one by one.
