vbscriptFileSystem Objects

Checking for the existence of a file/folder/drive

Methods used:

.DriveExists(strDrive) returns (True/False)
.FileExists(strFile) returns (True/False)
.FolderExists(strFolder) returns (True/False)

The following code checks for the existence of a file using the "FileExists" method of a file system object. For checking the existence of Folder or a drive, one can use the method "FolderExists" or "DriveExists" respectively.

Code:

Dim strPath, objFso
strPath = "C:\Users\GS\Desktop\tasks.txt"        'Enter the absolute path of the File/Folder/Drive
Set objFso = CreateObject("Scripting.FileSystemObject")

'Checking for the File's existence
If objFso.FileExists(strPath) then               'returns True if the file exists, else False
    Msgbox "File Exists!"
Else
    Msgbox "File does not Exist!"
End If
Set objFso = Nothing

Deleting an existing folder and creating a new Folder

Methods used:

.DeleteFolder(FileSpec, Force (True/False))
.CreateFolder(Path)
.DeleteFile(FileSpec, Force (True/False))

The following example illustrates the Deletion and creation of a folder using the methods "DeleteFolder" and "CreateFolder".

Code:

Dim strFolderPath, objFso
strFolderPath = "C:\Users\GS\Desktop\testFolder"
Set objFso = CreateObject("Scripting.Filesystemobject")

'Checking for the folder's existence and deleting it, if found
If objFso.FolderExists(strFolderPath) then
    objFso.DeleteFolder strFolderPath, True                   'True indicates forceful deletion
End If

'Creating a new Folder
objFso.CreateFolder strFolderPath

Set objFso = Nothing

Similarly, One can Delete a File using the "DeleteFile" method:

Dim strFilePath:strFilePath = "C:\Users\GS\Desktop\tasks.txt"
If objFso.FileExists(strFilePath) then
    objFso.DeleteFile strFilePath, True                      'true indicates forceful deletion
End If

Copying a File/Folder

Methods Used:

.CopyFile(Source, Dest [,Overwrite (True/False)]
.CopyFolder(Source, Dest [,Overwrite (True/False)]

The following code illustrates the use of CopyFile method to copy a file to a new location. The same thing can be achieved for the folders by using the CopyFolder method.

Code:

Dim objFso, strSourcePath, strDestPath
strSourcePath = "C:\Users\GS\Desktop\Source.txt"
strDestPath = "C:\Users\GS\Desktop\Dest.txt"
Set objFso = CreateObject("Scripting.FileSystemObject")
If objFso.FileExists(strSourcePath) then
    objFso.CopyFile strSourcePath, strDestPath, True              'True indicates the overwritting of the file at the destination path i.e, if the file already exists, it will be overwritten
End If
Set objFso = Nothing

Moving a File/Folder

Methods Used:

.MoveFile(Source, Dest)
.MoveFolder(Source, Dest)

The following code illustrates the use of MoveFile method to Move a file to a new location. The same thing can be achieved for the folders by using the MoveFolder method.

Code:

Dim objFso, strSourcePath, strDestPath
strSourcePath = "C:\Users\GS\Desktop\Source.txt"
strDestPath = "C:\Users\GS\Desktop\Folder\Dest.txt"
Set objFso = CreateObject("Scripting.FileSystemObject")
If objFso.FileExists(strSourcePath) then
    objFso.MoveFile strSourcePath, strDestPath
End If
Set objFso = Nothing

NOTE: We do not have any method of a filesystem object which allows us to rename a file. However, this can be achieved by MoveFile method by moving the file to the same location with a different name as shown below:

Dim objFso, strSourcePath, strDestPath
strSourcePath = "C:\Users\GS\Desktop\OldName.txt"
strDestPath = "C:\Users\GS\Desktop\NewName.txt"       'Location is same but the name is different
Set objFso = CreateObject("Scripting.FileSystemObject")
If objFso.FileExists(strSourcePath) then
    objFso.MoveFile strSourcePath, strDestPath
End If
Set objFso = Nothing

Object reference to a folder

Methods used:

.GetFolder(strPath) - Returns an object referring to the path

We can set an object reference to a folder using the getFolder method and perform different operations on them.

Code:

Dim strFolderPath, objFso, objFolder
strFolderPath = "C:\Users\GS\Desktop\LogsFolder"
Set objFso = CreateObject("Scripting.FileSystemObject")
Set objFolder = objFso.getFolder(strFolderPath)

'Accessing the Folder's Properties
Msgbox objFolder.Name                            'Returns the Folder's Name
Msgbox objFolder.Size                            'Returns the Folder's size in Bytes  
Msgbox objFolder.DateCreated                     'Returns the Folder's creation date 
Msgbox objFolder.DateLastModified                'Returns the Folder's last modified date
Msgbox objFolder.Path                            'Returns the Folder's Absolute Path

Dim objChildFolders
Set objChildFolders = objFolder.SubFolders       'Returns the collection of all subfolder 

Dim objChildFiles
Set objChildFiles = objFolder.Files              'Returns the collection of all files contained in the folder  

'Using the Folder's methods
objFolder.Copy strDestPAth, True                 'Copies the folder to path contained in strDestPath and overwrite Flag=True
objFolder.Delete True                            'Deletes the Folder; True indicates forceful Deletion
objFolder.Move strDestPath                       'Moves the Folder to the path contained in strDestPath variable 
objFolder.CreateTextFile strFileName, True       'Created a new text file inside the folder and overwrites the existing file(if it exists)
Set objChildFiles = Nothing
Set objChildFolders = Nothing
Set objFolder = Nothing
Set objFso = Nothing

Object reference to a File

Methods Used:

.GetFile(strPath) - Returns an object referring to a file.

We can set an object reference to a file using the getFile method and perform different operations on them.

Code:

Dim strFilePath, objFso, objFile
strFilePath = "C:\Users\GS\Desktop\LogsFolder\file.txt"
Set objFso = CreateObject("Scripting.FileSystemObject")
Set objFile = objFso.getFile(strFilePath)

'Accessing the File's Properties
Msgbox objFile.Name                            'Returns the File's Name
Msgbox objFile.Size                            'Returns the File's size in Bytes  
Msgbox objFile.DateCreated                     'Returns the File's creation date 
Msgbox objFile.DateLastModified                'Returns the File's last modified date
Msgbox objFile.Path                            'Returns the File's absolute path

'Using the File's Methods
objFile.Delete True                            'Forcefully deletes the File
objFile.Copy strDestPath, True                 'Copies the file to path contained in variable strDestPath
objFile.Move strDestPath                       'Moves the file to the path contained in the variable strDestPath
objFile.OpenAsTextStream mode                  'Opens the file as a text stream in either Read mode(mode=1), write mode(mode=2) or Append mode(mode=8)
Set objFile = Nothing
Set objFso = Nothing
