We can check whether a file is existsing in the file system or not, using a function 'FileExists' in the file system Object. This function takes an argument which is the name of the file with the complete path and will return a boolean value. 'True' means the file Exists; 'False' means the file doesn't Exist. The syntax of the 'FileExists' function is as follows

Syntax:
FileExists(filename)

'filename': Here the argument filename is the name of the file with complete path.

The following demonstrates how to check for a file.

Dim ObjFso
Dim StrFileName
Dim BoolResult

StrFileName = "C:\TestFile.txt"
Set ObjFso = CreateObject("Scripting.FileSystemObject")
BoolResult = ObjFso.FileExists(StrFileName)

If BoolResult = True Then
   WScript.Echo("The file exists.")
Else
   WScript.Echo("The file doesn't exists!!")
End If
