Project files backing up

Hi,

I saved a copy of complete folder of my worksets to the company server as backup after i finished a scenario running.

however, i found that some settings including the project material, E&M systems are lost when i draw back to rerun for checking. model setup is still there but other previous input information are all lost

can you advise the path and file name where these information are saved and i could get them back.

Thanks

Regards,

Brian
