FILE SYSTEM OBJECT

fso.html

FileSystemObject

• (^) The standard Visual Basic (VB) file input and output commands are not available in VBScript.
• (^) All the file access is provided through the methods and properties of special objects

FSO Objects (Contd…)

3. File  (^) (object) Contains methods and properties that allow us to create, delete or move a file. Also allows us to query the system for a file name, path and various other properties. 4. Files  (^) (Collection) provides a list of all files contained with in a folder.

5. Folder  (^) (object) Contains methods and properties that allow you to create, delete or move folders. Also allows us to query the system for folder names, paths and various other properties. 6. Folders  (^) (Collection) provides a list of all the folders within a folder.

• (^) The FSO is a kind of “Master Object” that serves as the access point for family of objects.
• (^) All of the objects in the FileSystemObject hierarchy together provide the functionality for accessing and manipulating window file system.

• (^) The root object “FileSystemObject” is the access point for all other objects.
• (^) To do anything on with drives, folders or files FileSystemObject must be created first.
• (^) Creating FileSystemObject
  • (^) Set FSO=CreateObject(“scripting.FileSystemObject”)

FSO object’s various methods

1. CreateFolder()
2. CreateTextFile()
3. GetFolder()
4. GetFile()
5. GetDrive()
6. CopyFolder()
7. MoveFolder()
   1. FolderExists()
   2. GetDriveName()
   3. GetExtensionName( )
   4. FileExists()

Creating a Folder

Dim FSO, FolderObj Set FSO= CreateObject(“scripting.FileSystemObject”) Set FolderObj=FSO.CreateFolder(“D:\ITA”);

GetFolder()

• (^) This method returns a folder object of the folder whose path is specified as parameter. Set FSO= CreateObject(“scripting.FileSystemObject”) Set FolderObj=FSO.GetFolder(“D:\ITA”);

GetFile()

• (^) This method returns a file object of the file whose path is specified as parameter. Set FSO= CreateObject(“scripting.FileSystemObject”) Set FileObj=FSO.GetFile(“D:\ITA\test.txt”);

CopyFolder()

FSO.CopyFolder source, destination dim FSO set FSO=CreateObject("Scripting.FileSystemObject") If FSO.FolderExists("c:\sourcefolder\website") Then FSO.CopyFolder "c:\sourcefolder\website", "c:
destfolder\” End If

MoveFolder()

FSO.MoveFolder source, destination

GetDriveName(path)

dim FSO, a Set FSO =CreateObject("Scripting.FileSystemObject") a = filesys.GetDriveName(“d:\ITA\test.txt”) ‘a=“d:”

GetExtensionName(path)

FSO.GetExtensionName(path)

• (^) Used to return a string containing the extension name of the supplied path.
• (^) If no extension found in the supplied path method will return an empty string.
