Accessing the File System
The FileSystemObject Object
The FileSystemObject object lets you create and work with files and directories on the server. For example, you can create a file, write data to it and then delete it when the file is no longer necessary. You can also determine whether or not certain files exist, as well as their locations, extensions and other information.

The following code determines whether or not a certain file (temp.txt) exists on the server and, if it does, deletes it:
|
<HTML>
<HEAD>
</HEAD>
<BODY>
<%
Dim varFileSystem
Set varFileSystem=Server.CreateObject("Scripting.FileSystemObject")
If varFileSystem.FileExists("c:\inetpub\wwwroot\temp.txt")=true then
varFileSystem.DeleteFile("c:\inetpub\wwwroot\temp.txt")
End If
%>
</BODY>
</HTML>
|
Once you've created a FileSystemObject object, you can use its methods to create instances of the TextStream object, the File object, the Folder object and the Drive object. All of these have methods and properties of their own that let you create and manipulate specific files, folders and drives on the server.
