smartRescue lets you repair working files that won't open anymore. It offers several so called steps that run over your working files to update them so that you should hopefully soon be back working in your files.
smartRescue can be run in Nuke and as a standalone application. We also provide baked executables that you just double click to launch.
If you have some programing knowledge, you can easily create your own steps and share them within others.
Enjoy smartRescue completely for free. You're welcome.
