I'm afraid exported projects are deliberately designed to be as hard to modify or understand as possible, to prevent reverse engineering, which lots of people don't want to be easily possible for their published games. You will need the Construct project to make modifications. You should keep regular backups for any important digital work you do, whether in Construct or other software - unfortunately sometimes that's a lesson you learn the hard way.

from now i make regularly backup

Thanx for reply ashley
