# Use VBScript to Silently Remove Empty Folders

This code will silently delete all empty folders in the given start folder using VBScript.

I decided to write this article after I saw an interesting question here on Experts Exchange by one of our new members, asking how to delete empty folders and subfolders in a directory without any prompts.

The script is well commented but I am going to outline the major portion of the code here.

1. Set the “Start Folder” - this will be the folder where you want to clean up all empty folders.  My example uses "C:\temp\ee\clean"

2. VBScript does not have very good array support so we have to use some tricks. I will be creating a collection of found folders and saving to a text field that will get delimited with a special delimiter that will not get confused with other possible characters in a folder name.  The field "txtFolderList" will hold the text list.

3. Here will run a subroutine that will recursively find all subfolders in our start folder. As folders are found, the folder names will be saved in "txtFolderList"

4. Here we are creating an array from our text field.  We will use the array to loop through all the found folders.

5. Finally, we call a subroutine for each folder in the array that will check if the folder is empty. If the folder is empty, it will get deleted. Note that we are starting with the last array object and going towards the first. The reason is the first folders will be filled with the last folders and will not be found as empty. By working backward, we check if the last item is empty and if it is, delete it. This allows the parent folders to be deleted if no other files are found.

The subroutines are well commented. The script will run wherever you can run VBScript (Windows). To run the script, save the file with the .vbs extension. From there you can use the command prompt or anything that can call a command line.

Assuming the file is called "clean.vbs" and is found in c:\scripts\clean.vbs, you only need to enter c:\scripts\clean.vbs to the command prompt or call the line in your own code.

' 1) THE FOLDER TO START
startFolder = "C:\temp\ee\empty1"

' 2) VARIABLE TO HOLD ALL FOUND FOLDERS
txtFolderList = ""

' CREATE FILE SYSTEM OBJECT
Set fso = CreateObject("Scripting.FileSystemObject")

' 3) CALL SUBROUTINE THAT WILL RECURSIVELY GET ALL SUB FOLDERS
getSubfolders fso.GetFolder(startFolder)

' WHEN txtFolderList IS POPULATED
' IT WILL LOOK LIKE c:\path\folder[|]c:\path\folder[|]c:\path\folder
' 4) CREATE AN ARRAY USING splut and [|] TO SEPARATE

arrSubFolders = split(txtFolderList,"[|]")

' 5) LOOP THROUGH ARRAY BACKWARDS
' ALLOWS TO DELETE THE LAST FOLDER FIRST
intArraySize = LBound(arrSubFolders) 'array size
For x = UBound(arrSubFolders) to 0 step -1 'LOOP THROUGH FOLDERS BACKWARDS
'RUN THE CLEAN ROUTINE FOR THE CURRENT SUBFOLDER

Next

'Wscript.Echo txtFolderList

' SUBROUTINE TO RECURSIVELY GET ALL SUB FOLDERS
Sub getSubfolders(Folder)

'LOOP THROUGH ALL SUB FOLDERS
For Each Subfolder in Folder.SubFolders

if txtFolderList = "" then 'IF THIS IS THE FIRST ENTRY

txtFolderList = Subfolder.Path 'ADD THE FIRST SUB FOLDER TO OUR txtFolderList

else

' CONTINUE TO ADD TO THE FIELD txtFolderList USING A DELIMINTER OF [|]
txtFolderList = txtFolderList &"[|]"& Subfolder.Path

end if

'CALL getSubfolders INSIDE THE LOOP TO GET MORE SUB FOLDERS

Next
End Sub

' SUB ROUTIE TO CHECK IF FOLDER IS EMPTY
' DELETE FOLDER IF IT IS EMPTY
sub clean(strFolder)

If fso.FolderExists(strFolder) Then 'MAKE SURE FOLDER EXISTS

Set objFolder = fso.GetFolder(strFolder) 'CREATE FOLDER OBJECT

' CHECK THAT FOLDER IS EMPTY (REASON WE ARE GOING BACKWARDS)
If objFolder.Files.Count = 0 And objFolder.SubFolders.Count = 0 Then

'DELETE FOLDER WHEN TRUE (EMPTY)
fso.DeleteFolder strFolder

end if

End If

end sub

set fso = nothing
