diskusage command analyze drive space windows


Hey there, readers! Are you finding yourself running out of drive space without knowing what’s taking it all up? Well, have no fear, because Windows has a built-in command that can help you analyze your drive space and identify the space hogs: the "diskusage" command. In this article, we’ll dive into the details of using this powerful tool to optimize your storage and keep your computer running smoothly.

Understanding the "diskusage" Command

The "diskusage" command is a command-line tool that provides a detailed analysis of disk space usage on a specific drive. It calculates the amount of space used by files and folders, allowing you to quickly identify the largest space consumers. To use the command, simply open the Command Prompt or PowerShell window and type "diskusage" followed by the drive letter you want to analyze.

Analyzing Drive Space with "diskusage"

Subheading 1: Displaying Space Usage in Tree View

The simplest way to use "diskusage" is to run it without any options. This will display a tree-like structure showing the amount of space used by each directory and file on the drive. By default, the output is sorted in descending order, with the largest space consumers at the top. This view is useful for getting a quick overview of your drive space usage.

Subheading 2: Filtering Results to Specific Directories

You can also use the "-d" option to filter the results to a specific directory or subdirectory. This is helpful if you want to focus on analyzing a particular part of your drive. For example, to analyze space usage within the "Downloads" folder, you would type:

diskusage -d "C:UsersUsernameDownloads"

Subheading 3: Excluding Certain File Types

If you want to exclude certain file types from the analysis, you can use the "-s" option followed by the file extension. For instance, to exclude files with the ".tmp" extension, you would use:

diskusage -s tmp

Table Breakdown: "diskusage" Command Options

Option Description
-d "directory" Analyzes space usage within a specific directory
-s "extension" Excludes files with a specific file extension from the analysis
-t Sorts the output by file size, with the largest files at the top
-e Sorts the output by file extension
-h Displays the output in a human-readable format with file sizes in gigabytes (GB) and megabytes (MB)


The "diskusage" command is an incredibly useful tool for analyzing drive space on Windows systems. By understanding how to use its various options, you can easily identify the files and folders that are taking up the most space and optimize your storage accordingly.
