Solution to Script : Pasting artwork is slow, includes unused data

I have a solution about 'many swatch' problem (http://helpx.adobe.com/illustrator/kb/copy-paste-artwork-slow-or.html)

1. Unlock all object (Ctrl+Alt+2)

2. select All object (Ctrl+A)

3. run script

principle is ...

(1) open new document

(2) copy selected object to new document

(3) save new document (XXX_new.ai)

I'm not good programmer. So I feel uneasy open my source code. But, It's maybe hint for your problem.

If it's not work, send AI file. I need variety test data.
