Help pls, in finding some .txt files.

Hi

I keep a couple of .txt files on my desktop, so I can easily refer to them.

Today I lost them. They are not in the recycle bin though, it has not been emptied since July, so, where can these files be please?

I have done a search for them, and they just seemed to have vanished without trace.

Please could someone help me locate them?

Thanks
