Why? Because the bloody XLS file I’ve been working on all week has disappeared up in smoke! Not in my recycle bin, not in my file history, not even where I KNOW I saved it (and have been opening it from all god-damn week). Excel’s auto-recover did not automatically recover this file. A search of all xls files on my computer does not find this file.
Any suggestions? It’s work, so Windows XP is the operating system.
