VBScript FileSystem Objects

As the name suggests, FSO Objects help the developers to work with drives, folders and files. In this section, we will discuss −

Objects and Collections

Sr.No.	Object Type & Description
1	Drive Drive is an Object. Contains methods and properties that allow you to gather information about a drive attached to the system
2	Drives Drives is a Collection. It Provides a list of the drives attached to the system, either physically or logically.
3	File File is an Object. It Contains methods and properties that allow developers to create, delete or move a file.
4	Files Files is a Collection. It Provides a list of all files contained within a folder.
5	Folder Folder is an Object. It Provides methods and properties that allow developers to create, delete or move folders.
6	Folders Folders is a Collection. It Provides a list of all the folders within a Folder.
7	TextStream TextStream is an Object. It enables developers to read and write text files.

Drive

Drive is an object, which provides access to the properties of a particular disk drive or network share. The Following properties are supported by Drive object −

AvailableSpace
DriveLetter
DriveType
FileSystem
FreeSpace
IsReady
Path
RootFolder
SerialNumber
ShareName
TotalSize
VolumeName

Example

<!DOCTYPE html>
<html>
   <body>
      <script language = "vbscript" type = "text/vbscript">
         Dim oFS, drive, space
         Set oFS = CreateObject("Scripting.FileSystemObject")
         Set drive = oFS.GetDrive(oFS.GetDriveName("C:\"))
         space = "Drive " & UCase(drvPath) & " - " 
         space = space & drive.VolumeName   & "  "
         space = space & "Free Space: " & FormatNumber(drive.FreeSpace/1024, 0) 
         space = space & " Kbytes"
         Document.write space

      </script>
   </body>
</html>

If the above script is saved as HTML and executed in IE, we would get the following output in the console.

Drive - Win 7 Free Space:20,154,059 Kbytes

Drives

Drives is a collection, which provides details of all the drives attached to the system, either physically or logically. It carries two properties −

Count Property
Item Property

Example

<!DOCTYPE html>
<html>
   <body>
      <script language = "vbscript" type = "text/vbscript">
         Dim oFS, d, dc, s, n
         Set oFS = CreateObject("Scripting.FileSystemObject")
         Set dc = oFS.Drives
         
         For Each d in dc
            n = ""
            s = s & d.DriveLetter & " - " 
            If d.DriveType = 3 Then
               n = d.ShareName
            ElseIf d.IsReady Then
               n = d.VolumeName
            Else
               n = "Drive not available"
            End If
            s = s & n & "::"
         Next
         
         document.write s
         document.write dc.count
         
      </script>
   </body>
</html>

If the above script is saved as HTML and executed in IE, we would get the following output in the console.

Folders

Folders is an collection of all Folder Objects within a Folder object.

Methods

Properties

Count
Item

Example

If the above script is saved as HTML and executed in IE, we would create a folder with name "Test_Folder".

<!DOCTYPE html>
<html>
   <body>
      <script language = "vbscript" type = "text/vbscript">
         Dim fso, f, fc, nf
         Set fso = CreateObject("Scripting.FileSystemObject")
         Set f = fso.GetFolder("D:\PROJECT")
         Set fc = f.SubFolders
         folderName = "Test_Folder"
         
         If folderName <> "" Then
            Set nf = fc.Add(folderName)
         Else
            Set nf = fc.Add("New Folder")
         End If
         
      </script>
   </body>
</html>

TextStream

TextStream object helps the developers to work with text files seamlessly. Developers can read, write or append the contents to the text file using the text stream object.

Syntax

TextStream.{property  | method( )}

Example

If the above script is saved as HTML and executed in IE, we would create a folder with name "Test_Folder".

<!DOCTYPE html>
<html>
   <body>
      <script language = "vbscript" type = "text/vbscript">
         Dim objFSO
         Set objFSO = CreateObject("Scripting.FileSystemObject") 
         
         Dim objTextFile 
         Set objTextFile = objFSO.CreateTextFile("D:\Testfile.txt") 
         
         objTextFile.Close
         Const ForAppending = 8
         Set objTextFile = objFSO.OpenTextFile("D:\Testfile.txt",ForAppending,True)
         
         objTextFile.WriteLine "Welcome to VBScript Programming"
         objTextFile.Close
         Set objTextFile = Nothing 
         Set objFSO = Nothing 
         
      </script>
   </body>
</html>

If the above script is saved as HTML and executed in IE, it will create a text file in D:\ Drive and append the string specified in the WriteLine Method.
