Introduction
Hey readers, welcome to our comprehensive guide on using the ‘diskusage’ command to analyze disk space usage in Windows. This nifty command provides a detailed breakdown of what’s taking up space on your hard drive, helping you identify areas for potential optimization. Let’s dive right in and explore the ins and outs of this command.
Understanding the ‘diskusage’ Command
The ‘diskusage’ command is a built-in tool in Windows that displays a hierarchical summary of file and directory usage. It’s a command-line utility that can be accessed through the Command Prompt or PowerShell. By default, it analyzes the current working directory, but you can specify specific paths or drives for a more targeted analysis.
Using the ‘diskusage’ Command
To use the ‘diskusage’ command, simply type ‘diskusage’ followed by the path you want to analyze. For example, to analyze the C: drive, you would enter:
diskusage C:
The output will provide a tree-like structure showing the size of each directory and its subdirectories. You can navigate through the directory structure using arrow keys or page up/down, and press ‘q’ to exit.
Interpreting the ‘diskusage’ Output
The ‘diskusage’ output consists of several columns:
- Size: The total size of the directory or file in bytes.
- % of Total: The percentage of the total analyzed space that the directory or file occupies.
- Logical: The number of files and directories in the directory.
- Path: The full path to the directory or file.
By examining the output, you can quickly identify large directories and files that are consuming the most space. This can help you make informed decisions about what to clean up or move to another location.
Excluding Certain Directories
In some cases, you may not want to include certain directories in the analysis. To exclude a directory, use the ‘/s’ (skip) switch followed by the path. For example, to exclude the "Program Files" directory:
diskusage C: /s "Program Files"
Analyzing Remote Network Shares
The ‘diskusage’ command can also be used to analyze disk space usage on remote network shares. To do this, use the ‘/n’ (network) switch followed by the UNC path. For example, to analyze the "Shared Documents" folder on a remote server:
diskusage serverShared Documents
Advanced Features of the ‘diskusage’ Command
Filtering the Output
The ‘diskusage’ command supports filtering the output based on specific criteria. Use the ‘/f’ (filter) switch followed by the filter expression. For example, to filter for files larger than 100MB:
diskusage C: /f size>100000000
Sorting the Output
You can also sort the output in ascending or descending order by specifying the ‘/o’ (order) switch. Use the ‘+/-‘ prefix to indicate ascending or descending, respectively. For example, to sort the output by size in descending order:
diskusage C: /o -size
Conclusion
The ‘diskusage’ command is a powerful tool for analyzing disk space usage in Windows. By understanding the command’s options and interpretations, you can effectively identify areas for optimization and ensure the efficient use of your hard drive space.

FAQ about "diskusage Command Analyze Drive Space Windows"
1. What is the diskusage command?
The diskusage command is a Windows command-line tool that provides information about the usage of disk space on a specified drive.

To use the diskusage command, open a Command Prompt or PowerShell window and type the following command:
diskusage [drive letter:]
3. What does the diskusage command output?
The diskusage command outputs a table that shows the following information for each drive specified:
- Drive letter: The letter assigned to the drive.
- Total size: The total size of the drive in megabytes (MB).
- Available space: The amount of free space available on the drive in MB.
- Used space: The amount of space used on the drive in MB.
- Percentage used: The percentage of the drive that is used.
4. How can I see more detailed information about the usage of disk space?
To see more detailed information about the usage of disk space, you can use the following options with the diskusage command:
- -a: Displays a list of all files and folders on the drive, sorted by size.
- -c: Displays a summary of the number of files and folders on the drive.
- -e: Displays a list of all Empty folders on the drive.
- -f: Displays a list of all Large files on the drive.
5. What is the difference between the "Used Space" and "Available Space" columns?
The "Used Space" column shows the amount of space on the drive that is currently being used by files and folders. The "Available Space" column shows the amount of free space on the drive that is available for new files and folders.
6. Why is the "Used Space" column different from the sum of the sizes of all the files and folders on the drive?
The "Used Space" column includes the space used by the file system, as well as by hidden files and folders.
7. How can I free up disk space?
You can free up disk space by deleting unnecessary files and folders, or by moving them to another drive. You can also use the Disk Cleanup tool in Windows to remove temporary files and other unnecessary items.
8. Why is the "Available Space" column not increasing after I delete files and folders?
The "Available Space" column may not increase after you delete files and folders because the file system may not have reclaimed the space occupied by the deleted files and folders. To reclaim the space, you can defragment the drive.
9. How can I defragment a drive?
You can defragment a drive using the Defragment and Optimize Drives tool in Windows.
10. What is the "-s" option?
The "-s" option displays a summary of the disk space usage for all drives on the system.
