Programming | Advanced 1. Folder Object
The RootFolder property of the driver object returns a Folder object through which all content in the drive can be accessed. You can use the properties and methods of this Folder object to traverse the directory on the drive and get the properties of that folder and other folders.
(1) Properties of the Folder object
A Folder object provides a set of properties that you can use to get more information about the current folder or to change the name of the folder. Its properties and descriptions are shown in table 5-9:
Table 5-9 Properties and descriptions of Folder objects
Property
Description
Attributes
Returns the properties of a folder. Can be one or a combination of the following values: Normal (0), ReadOnly (1), Hidden (2), System (4), Volume (name) (8), Directory (folder) (16), Archive (32), Alias (64 ) and Compressed (128). For example, a hidden read-only file with a value of 3 attributes
DateCreated
Returns the date and time the folder was created
Datelastaccessed
Returns the date and time the folder was last accessed
DateLastModified
Returns the date and time the folder was last modified
Drive
Returns the drive letter of the drive where the folder is located
Files
Returns the Files collection contained in a Folder object that represents all of the file
IsRootFolder
Returns a Boolean value indicating whether the folder is the root folder of the current drive
Name
Sets or returns the name of a folder
ParentFolder
Returns the folder object corresponding to the parent folder
Path
Returns the absolute path to the folder, using the appropriate long file name
ShortName
Returns the DOS-style folder name in 8.3 form
ShortPath
Returns the absolute path of a DOS-style 8.3-form folder
Size
Returns the size of all files and subfolders contained in this folder
Subfolers
Returns the Folders collection for all subfolders contained within the folder, including hidden folders and system folders
Type
If possible, return a description string for a folder (for example, "Recycle Bin")
(2) Method of folder object
The folder object provides a set of methods that can be used to copy, delete, and move the current folder. These methods run the same way as the CopyFolder, Delefolder, and MoveFolder methods of the FileSystemObject object, but these methods do not require the source parameter because the source file is this folder. These methods and descriptions are shown in table 5-10:
Table 5-10 the method and description of Folder object
Method
Description
Copy (Destination,overwrite)
Copy this folder and all the contents to the folder specified by destination. If the end of the destination is a path delimiter (' \ '), the destination is considered to be a folder where the copy folder is placed. Otherwise think destination is the path and name of the new folder you want to create. If the destination folder already exists and the overwrite parameter is set to False, an error is generated and the default overwrite parameter is True
Delete (Force)
Delete the folder and all the contents inside it. If the optional force parameter is set to True, the folder is deleted even if the folder is set to read-only or contains a read-only file. The default force is False
Move (destination)
Move the folder and all of its contents to the folder specified by destination. If the end of the destination is a path delimiter (' \ '), the destination is considered to be a folder where the mobile folder is placed. Otherwise think destination is the path and name of a new folder. An error occurs if the destination folder already exists
CreateTextFile
(Filename,overwrite,unicode)
Creates a new text file in the folder with the specified file name, and returns a corresponding TextStream object. If the optional overwrite parameter is set to True, any existing file of the same name will be overwritten. The default overwrite parameter is False. If the optional Unicode parameter is set to True, the contents of the file are stored as Unicode text. The default Unicode is False
You can use the ParentFolder property of the current folder between folders to return to the parent directory. When a folder is reached, if the IsRootFolder property is true, stop. Leaves the root of the drive, along the directory tree, to traverse or access the specified folder within the Folders collection (returned by the subfolders property of the current folder).
The following program iterates through all the folders in the root directory of drive C and displays information about each folder.
The VBScript procedure is as follows:
' In VBScript:
' Create a FileSystemObject instance
Set objFSO = Server.CreateObject ("Scripting.FileSystemObject")
' Get a reference to drive C
Set Objdrivec = objfso.getdrive ("C:")
' Get a reference to the ' root folder
Set Objroot = Objdrivec.rootfolder
' Get a reference to the subfolders collection
Set objfolders = objroot.subfolders
' Get a reference to the ' subfolders collection
For each objfolder in Objfolders
Set ObjFolder1 = Objfolders.item ((objfolder.name))
Exit for
Next
' Iterate through all of the files in this folder
For each objfile in Objfolder1.files
Response.Write "Name:" & Objfile.name & ""
Response.Write "ShortName:" & Objfile.shortname & ""
Response.Write "Size:" & objfile.size & "bytes"
Response.Write "Type:" & Objfile.type & "<BR>"
Response.Write "Path:" & Objfile.path & ""
Response.Write "ShortPath:" & Objfile.shortpath & "<BR>"
Response.Write "Created:" & objfile.datecreated & ""
Response.Write "LastModified:" & objfile.datelastmodified & "<P>"

The JScript program is as follows:
