If thats the problem then open any other attach files and click save as instead of save. When you do so your computer will display the path where the file is going to be stored. It looks something like c:/window/documents/... Note the path and follow it by clicking accordingly. For example go to c drive then click window then click documents and so on. Its more likely that the file your searching will be located at the same place unless u've delated by mistake.

Hopefully it will work for you. good luck.
