'In Visual Basic 

Dim FileName = "newfile.xml" ' The Name of file with its Extension Example A.txt or A.xml

Dim FilePath ="C:\MyFolderName" & "\" & FileName  'First Name of Directory and Then Name of Folder if it exists and then attach the name of file you want to search.

If System.IO.File.Exists(FilePath) Then
    MsgBox("The file exists")
Else
    MsgBox("the file doesn't exist")
End If

Dim SourcePath As String = "c:\SomeFolder\SomeFileYouWantToCopy.txt" 'This is just an example string and could be anything, it maps to fileToCopy in your code.
Dim SaveDirectory As string = "c:\DestinationFolder"

Dim Filename As String = System.IO.Path.GetFileName(SourcePath) 'get the filename of the original file without the directory on it
Dim SavePath As String = System.IO.Path.Combine(SaveDirectory, Filename) 'combines the saveDirectory and the filename to get a fully qualified path.

If System.IO.File.Exists(SavePath) Then
   'The file exists
Else
    'the file doesn't exist
End If
