Help: lost suddenly all the previous work!

Hi guys,

I really need your help: I do not know what happened, I have quit STATA in the same way but, when I reopened it again I could not find anymore the data set I was working with.
I clicked on File> Open Recent and instead of finding the files I was working with I just found

which I don't know what it is and anyway it just has a part of data I was working with...
Has it ever happened to you before?
Any idea where I could look for the previuos file?
Obviously, I have already tried the option Search but i could not find them...
Please help me because I am really lost!

I don't use Stata but I'm sure if you posted your solution if anybody in the future has the same problem it could help them out.
