When a file is deleted or overwritten it may still be in the 'Recycle bin'.
You could use the search facility in Windows Explorer to look for the file
either by the name of the file or word or phrase in the file. This will
show whether the file is available anywhere on the hard disk.
However, it may be still available. This is because it is only a reference
to the position of the file on the hard disk that is deleted not the data
itself. At this point the chances of recovery decrease dramatically. As
you use the computer there is a chance that some or all of your file will be
overwritten. You may like to use something like Restoration, available free
from -
http://www.snapfiles.com/get/restoration.html.
It is strongly advised to download and install this on another hard disk (if
available) to decrease the possibility of overwriting your file.
