在文件夹之间可以使用当前文件夹的ParentFolder属性，返回到父目录。当到达一个文件夹时，如果IsRootFolder属性是True，就停下来。离开驱动器的根目录，沿目录树向下，可遍历或访问在Folders集合（由当前文件夹的SubFolders属性返回）内的指定文件夹。
下列程序遍历了驱动器C根目录内的所有文件夹，并显示各个文件夹的有关信息。
VBScript程序如下：
'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 first folder in the SubFolders collection
For Each objFolder In objFolders
Set objFolder1 = objFolders.Item((objFolder.Name))
Exit For
Next
' Iterate through all 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>"
Next
JScript程序如下：
//In JScript:
// Create a FileSystemObject instance
var objFSO = Server.CreateObject('Scripting.FileSystemObject');
// Get a reference to drive C
var objDriveC = objFSO.GetDrive('C:');
// Get a reference to the root folder
var objRoot = objDriveC.RootFolder;
// Get a reference to the first folder in the SubFolders collection
var colAllFolders = new Enumerator(objRoot.SubFolders);
var objFolder1 = colAllFolders.item();
// Get a reference to the Files collection for this folder
var colFiles = new Enumerator(objFolder1.Files);
