There is no data and engine folders in simple jquery modal

Q: I used visual light box 5 years ago to develop picture pages for my website. When the visual light box folder was created it had a DATA & ENGINE file. I recently purchased the software again from you and I am not getting those files?? Has something changed I don't know about? I need them to put into the smart FTP client. HELP!!!!

A: These folders were combined into index_files folder. You should upload this folder into your server.
