What I am trying to do is equivilant to an IfExist in C
I can Create - Append - and Read from a Disk File from with in the Code.
I can Also open an File/Directory (Save IN ....) dialog Box
What I want to do is Have the program check to see if the FILENAME exist prior to overwriting the file with in the code

In general, you can do something like:

 

Sub MyFunction()
On Error GoTo FailedToReadFile
    ' Read File Code
On Error GoTo FailedToWriteToFile
    ' Write File Code
ExitMyFunction:
Exit Sub
FailedToReadFile:
    ' Read File Error Handling
    GoTo ExitMyFunction
FailedToWriteToFile:
    ' Write File Error Handling
    GoTo ExitMyFunction
End Sub
