In vb script we can check whether a file exists or not using the 'FileExists' function in File System Object. The syntax of FileExists function is given below
FileExists ( FileName )
Following example demonstrates how to check for the existence of a file
Dim fs
Set fs = CreateObject("Scripting.FileSystemObject")
If fs.FileExists("C:\File-1.txt") Then
WScript.Echo("File Exists!!")
Else
WScript.Echo("File Does not Exist")
End If
