lost source code

 
good day.

I lost a particular version of my EA, that I really need. 
is it possible to retrieve log file of changes made to an EA, in history some how and I try and navigate my way back the changes. 

is there another way I can retreive the Code. 
my earlier version was 61KB when compiled however the current one is 94KB 
 
not possible
 
Jefferson Metha: is there another way I can retreive the Code.
Go to your backups. You do backup your system, don't you? //www.youtube.com/watch?v=l7-6m2cE6JM
 

If you still have MetaEditor open you can press ctrl+Z to revert your changes step by step back to the point where you opened the file.

Press ctrl+Y to move forward a step in time.
 
I had a backup from 5 March and one from 11 March in storage I had to go into my mind Palace and get the version I wanted. 

Thank you all.
