FileSystemObject object

<Body>
<%
Set fs = Server. CreateObject ("Scripting. FileSystemObject ")
If (fs. FileExists ("c: \ windows \ cursors \ xxx. cur") = true Then
Response. Write ("file c: \ windows \ cursors \ xxx. cur exists. ")
Else
Response. Write ("file c: \ windows \ cursors \ xxx. cur does not exist. ")
End If
Set fs = nothing
%>
</Body>
</Html>

The running result of this instance is as follows:

File c: \ windows \ cursors \ xxx. cur does not exist.

Does the specified folder exist?

The sample code is as follows:

Reference content is as follows:

<Html>
<Body>
<%
Set fs = Server. CreateObject ("Scripting. FileSystemObject ")
If fs. FolderExists ("c: \ temp") = true Then
Response. Write ("folder c: \ temp exists. ")
Else
Response. Write ("folder c: \ temp does not exist. ")
End If
Set fs = nothing
%>
</Body>
