System crashed , I saved but file is gone.

I’m running a old A20m thinkpad with tiny core installed on hardrive. Things bugged up and my o.s crashed but I did save my file but before I could move it to my removable device, …my o.s crashed.
On reboot the file is gone, there is no backup folder in 4/user path.

Is my story gone?
Might be because I didn’t back up tiny core but it’s installed on the hardrive. I think I’m doing something wrong.
