Please Note: This article is written for users of the following Microsoft Excel versions: 2007 and 2010. If you are using an earlier version (Excel 2003 or earlier), this tip may not work for you. For a version of this tip written specifically for earlier versions of Excel, click here: Retrieving Drive Statistics.
If you are creating a full-blown application using Excel, you may want to know a bit about the environment in which your application is running. For instance, you might want to know how many drives are attached to the system, what their drive letters are, and how much space they have free.
The following macro will retrieve the requested information. All you need to do is provide the column headings. The macro assumes that you'll have three columns: In cell A1 you should place the heading "Drive," in cell B1 you place the heading "Free%," and in cell C1 you place the heading "Used%." In addition, you should format columns B and C as percentages.
Sub DriveSizes() Dim Drv As Drive Dim fs As New FileSystemObject Dim Letter As String Dim Total As Variant Dim Free As Variant Dim FreePercent As Variant Dim TotalPercent As Variant Dim i As Integer On Error Resume Next i = 2 For Each Drv In fs.drives If Drv.IsReady Then Letter = Drv.DriveLetter Total = Drv.TotalSize Free = Drv.FreeSpace FreePercent = Free / Total TotalPercent = 1 - FreePercent Cells(i, 1).Value = Letter Cells(i, 2).Value = FreePercent Cells(i, 3).Value = TotalPercent i = i + 1 End If Next End Sub
When you first run this macro, you may get an error. If you do, it means that you need to configure your macro to reference the Microsoft Scripting Runtime. Follow these steps from within the VBA Editor:
Now the macro should run just fine, and you will have a fully populated table representing all the drives available on your system. (If your system has drives that use removable media—such as floppy drives—they may not show up unless you have media in them.)

Not all that. But you can return TotalSize (bytes) and DriveType (Unknown, Removable, Fixed, Network, CD-ROM, RAM Disk). My SSD is called Fixed, not RAM Disk. See https://learn.microsoft.com/en-us/office/vba/language/reference/user-interface-help/drive-object

Is there any other information that can be pulled? For instance Drive Make, Model, Size (in Gb or Tb), Physical size (3.5 in, 2.5), Speed (5400), SSD, etc.

"Dim Drv As Drive" failed with "User defined type not defined"
Presumably some other instruction needs to be added to define the DRIVE type

On one hard disk you can have several partitions and they have each their own drive letter and they each have their used and unused percentages even if each drive has it's own entire physical disk. I have no experience with servers but I suppose that it will be the same.

Ignore my last question. I just realized that most of the "drives" I have are all on one server and obviously they are all the same amount of free space, since it is on the same hard drive.

Great for Drive letters! Thanks! How easy would it be to change the macro to do the root folders on a server (even the ones you are not naturally assigned a drive letter to)?

You're welcome! I remember how excited I was too when I realized it could be that simple. :)

@ Locke Garmin:
Thank you SO MUCH for that tip! Up to now I have been using one line of code per cell to assign column headers.
Not any more!!!

One thing I like to do is add header columns in the macro in this way:
Range("A1:C1") = Array("Drive", "Free%", "Used%")

Very nice tip.
I love how powerful FSOs are, you can pretty much do anything with them.
Got a version of Excel that uses the ribbon interface (Excel 2007 or later)? This site is for you! If you use an earlier version of Excel, visit our ExcelTips site focusing on the menu interface.
