is there any way to restore our deleted files???

hi.i’m in an emergency i have worked on a project for a week and i only had one save of it(one save of each sequence).because it takes too long to save for the first time.to prepare next sequence for editing,i do things in the previous sequence and when it is done i save as the new sequence.the problem is i have saved it on the previous project i had completed and worked on it for a week.is there any way to bring back my layers and drawings or not???since harmony save anything that we remove!!!
please help me it is so important.

and another thing sometimes when i oppen my saved file i see that some of its drawings are blank.so i always have two layers in each project why is that???

I don’t believe so. sorry.
