When searching for temporary files in Windows, i.e. you have lost a file which you may have opened in Email, Word, Execl or other Software
Open Windows Explorer (Documents, Computer etc.)
Click tools –> Options
(Hint: If you cannot see tools at the top press the ALT key on the keyboard once)
Click to show Hidden Files
and also
Unclick Hide Operating Files
Click OK
Click on the C Drive and find temp file folder.
In Windows XP it should be here
C:\Documents and Settings\USERNAME\Local Settings\Temp
In Windows Vista it should be here C:\Users\USERNAME\AppData\Local\Temp
Now click search and type in an * followed by the name of the file excluding the first character and another * at the end (do not put any spaces)
e.g. your search for cv.doc would be *v.doc*
