What are folder objects in ASP?

We can use the Folder object in ASP to access all information regarding a specific folder. The object contains collections, properties, and methods that we can use to return relevant information.

To access the properties of a Folder object, we must first obtain a Folder object.

Obtaining a Folder object

We obtain a Folder object using the GetFolder() method of a FileSystemObject.

We can instantiate a Folder object as follows:

'Declare variables
Dim file_sys, folder_obj, message

'Define FileSystemObject
Set file_sys = Server.CreateObject("Scripting.FileSystemObject")

'Obtain Folder object
Set folder_obj = file_sys.GetFolder("c:\test")

Collections, properties, and methods

The Folder object contains collections, properties, and methods to add to its functionality.

Collections

The Folder object contains the following collections:

1. Files: Returns a collection of all the files in a specific folder.

2. SubFolders: Returns a collection of Folder objects within a specific Folder.

Dim file_sys, folder_obj, file
Set file_sys = Server.CreateObject("Scripting.FileSystemObject")
Set folder_obj = file_sys.GetFolder("c:\test\")

for each file in folder_obj.files
  'Print the name of all files in the Folder
  Response.write(file.Name & "<br>")
next

Set folder_obj = nothing
Set file_sys = nothing

Output

file1.txt
file2.txt
file3.txt

Properties

There are several properties associated with a Folder object.

Some of these include:

• Attributes: Sets or returns the attributes of a folder.

• DateCreated: Returns the date and time when a specific folder was created.

• ParentFolder: Returns the parent folder of a folder.

• Name: Sets or returns the name of a folder.

• Size: returns the size of a folder.

'Declare variables
Dim file_sys, folder_obj, message

'Define FileSystemObject
Set file_sys = Server.CreateObject("Scripting.FileSystemObject")

'Obtain Folder object
Set 
folder_obj = file_sys.GetFolder("c:\test")

'Creating response message
message = folder_obj.DateCreated
Response.Write("Folder created: " & s)

'Deallocating
set folder_obj = nothing
set file_sys = nothing

Ouput

Folder created: 08/10/2012 10:01:26 AM
