VBScript GetDrive Method

last modified April 9, 2025

The GetDrive method in VBScript is part of the FileSystemObject. It returns a Drive object corresponding to a specified drive. This method allows access to drive properties like free space, total size, and drive type. It’s essential for scripts that need to interact with storage devices.

GetDrive can work with drive letters, UNC paths, or mapped network drives. It provides detailed information about storage media. This tutorial covers GetDrive with practical examples to demonstrate its usage.

GetDrive Method Overview

The GetDrive method takes one parameter: a drive specification. It returns a Drive object with properties and methods. The drive specification can be a letter, path, or network share. This method is available through the FileSystemObject.

Key features include access to drive capacity, file system type, and volume information. It works with local and network drives. Understanding this method helps create robust storage management scripts. The method raises an error if the drive doesn’t exist.

Basic Drive Information

This example demonstrates the simplest use of GetDrive to retrieve basic information about a drive. It shows how to access common drive properties. The script displays the drive letter, type, and file system.

basic_getdrive.vbs

Set fso = CreateObject(“Scripting.FileSystemObject”) Set drive = fso.GetDrive(“C:”)

WScript.Echo “Drive Letter: " & drive.DriveLetter WScript.Echo “Drive Type: " & drive.DriveType WScript.Echo “File System: " & drive.FileSystem

Set drive = Nothing Set fso = Nothing

The script creates a FileSystemObject and calls GetDrive for the C: drive. It then displays three key properties. DriveType returns a number representing the drive type (2 for fixed drive). FileSystem shows the format (NTFS, FAT32, etc.).

Checking Drive Free Space

This example shows how to check available space on a drive using GetDrive. It demonstrates accessing capacity-related properties. The script calculates free space in gigabytes for better readability.

drive_space.vbs

Set fso = CreateObject(“Scripting.FileSystemObject”) Set drive = fso.GetDrive(“C:”)

totalGB = drive.TotalSize / (1024^3) freeGB = drive.FreeSpace / (1024^3)

WScript.Echo “Total Size: " & FormatNumber(totalGB, 2) & " GB” WScript.Echo “Free Space: " & FormatNumber(freeGB, 2) & " GB”

Set drive = Nothing Set fso = Nothing

The script retrieves the C: drive and calculates its total and free space. The values are converted from bytes to gigabytes for readability. FormatNumber displays the results with two decimal places. This is useful for disk monitoring scripts.

Working with Network Drives

GetDrive can access information about mapped network drives. This example shows how to retrieve properties from a network share. The script checks if a network drive is ready before accessing its properties.

network_drive.vbs

Set fso = CreateObject(“Scripting.FileSystemObject”) Set drive = fso.GetDrive(“Z:”)

If drive.IsReady Then WScript.Echo “Share Name: " & drive.ShareName WScript.Echo “Volume Name: " & drive.VolumeName Else WScript.Echo “Drive Z: is not ready” End If

Set drive = Nothing Set fso = Nothing

The script attempts to access a mapped network drive (Z:). It first checks the IsReady property to avoid errors. If ready, it displays the share and volume names. This approach is essential for reliable network drive access.

Listing All Available Drives

This example demonstrates how to list all available drives on a system. It combines GetDrive with the Drives collection. The script shows each drive’s letter and type in a readable format.

list_drives.vbs

Set fso = CreateObject(“Scripting.FileSystemObject”) Set drives = fso.Drives

For Each drive In drives WScript.Echo “Drive: " & drive.DriveLetter & " - Type: " & GetDriveTypeName(drive.DriveType) Next

Function GetDriveTypeName(typeNum) Select Case typeNum Case 0: GetDriveTypeName = “Unknown” Case 1: GetDriveTypeName = “Removable” Case 2: GetDriveTypeName = “Fixed” Case 3: GetDriveTypeName = “Network” Case 4: GetDriveTypeName = “CD-ROM” Case 5: GetDriveTypeName = “RAM Disk” Case Else: GetDriveTypeName = “Unknown” End Select End Function

Set drives = Nothing Set fso = Nothing

The script enumerates all drives using the Drives collection. For each drive, it displays the letter and a human-readable type. The helper function GetDriveTypeName converts numeric types to strings. This provides a comprehensive view of all storage devices.

Checking Drive Readiness and Type

This example shows advanced usage of GetDrive to check drive status. It demonstrates handling different drive types and readiness states. The script provides detailed information about each drive’s availability.

drive_status.vbs

Set fso = CreateObject(“Scripting.FileSystemObject”) Set drives = fso.Drives

For Each drive In drives WScript.Echo “Drive " & drive.DriveLetter & “:” WScript.Echo " Type: " & GetDriveTypeName(drive.DriveType)

If drive.IsReady Then
    WScript.Echo "  Status: Ready"
    WScript.Echo "  File System: " & drive.FileSystem
    WScript.Echo "  Free Space: " & FormatNumber(drive.FreeSpace / (1024^2), 2) & " MB"
Else
    WScript.Echo "  Status: Not Ready"
End If

Next

’ Same GetDriveTypeName function as previous example

Set drives = Nothing Set fso = Nothing

The script checks each drive’s readiness before attempting to access properties. For ready drives, it shows detailed information including free space in megabytes. This approach prevents errors when accessing unavailable drives. It’s particularly useful for scripts dealing with removable media.
