Danath, I faced the same problem not only once but several times not only with tomb raider stuff projects. Things with university, personal works.. etc.. it's really annoying
I have configured windows to be restored under certain point. This way you can get a backup of all personal files before a point and maybe if you commit such mistake, you are saved.
Take a look at restore or backup system and how yo configure them, for a next time just in case.
