How to get the Folder Size in VB.NET
My problem was not really big, but it was a problem which really irritated me a lot!!
We store data based on the user's alias in a folder called D:\SomeFolder on remote machine. In due course of time though, the hard disk starts giving No Disk Space problems, and we need to ask the users to delete the obsolete data. If they do it religiously, that's never a problem :o) So, all in all it is pretty time consuming to find out who is consuming the most amount of Disk Space. Here is what this utility does for me...
1. Prints the aliases of all the guys who are not freeing obsolete data in one line so that it is easy to send emails :o)
2. Prints the amount of space being consumed by that guy!
You can download the tool from this link.
Here is how the code is written for a file called FolderSize.vb. Just create a new Project and add a form called FolderSize. Go to the code view and paste the following...
Imports System.IO
Public Class FolderSize
Inherits System.Windows.Forms.Form
#Region " Windows Form Designer generated code "
Public Sub New()
MyBase.New()
'This call is required by the Windows Form Designer.
InitializeComponent()
'Add any initialization after the InitializeComponent() call
End Sub
'Form overrides dispose to clean up the component list.
Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
If disposing Then
If Not (components Is Nothing) Then
components.Dispose()
End If
End If
MyBase.Dispose(disposing)
End Sub
'Required by the Windows Form Designer
Private components As System.ComponentModel.IContainer
'NOTE: The following procedure is required by the Windows Form Designer
'It can be modified using the Windows Form Designer.
'Do not modify it using the code editor.
