Serveurs de fichiers - Episode 13 - Libérer de l'espace disque sous Windows Server 2022

Introduction

In this tutorial, we will explore effective methods to free up disk space on Windows Server 2022. Disk space issues are common, whether you're dealing with system volumes or data volumes. This guide provides practical tips and tools that can also apply to Windows 10 and Windows 11.

Step 1: Use the Disk Cleanup Tool

The Disk Cleanup tool is a built-in utility that helps remove unnecessary files and free up space.

1. Open the Start Menu and search for "Disk Cleanup."
2. Select the drive you want to clean (typically C: for system files).
3. Click "OK" to allow the tool to calculate space that can be freed.
4. Review the list of file types to delete, such as:
   • Temporary files
   • Recycle Bin
   • System files
5. Check the boxes next to the file types you want to remove.
6. Click "OK" and confirm the deletion.

Tips

• Regularly run Disk Cleanup to maintain optimal disk space.
• Consider using the "Clean up system files" option for deeper cleaning.

Step 2: Analyze Disk Usage with WinDirStat

WinDirStat is a useful tool for visualizing disk space usage.

1. Download and install WinDirStat from the official website.
2. Launch the application and select the drive you wish to analyze.
3. Wait for it to scan and display a graphical representation of file usage.
4. Identify large files or folders that are taking up significant space.

Common Pitfalls

• Make sure to review the files before deleting them, as some may be important for system functionality.

Step 3: Use TreeSize Free

TreeSize Free is another tool that provides detailed information about disk space usage.

1. Download and install TreeSize Free from the official site.
2. Open the application and select the drive you want to investigate.
3. Review the sizes of folders and files to determine what can be removed.
4. Right-click on any large file or folder and choose "Delete" to remove it.

Practical Advice

• Use TreeSize to track large files regularly to keep disk space in check.

Step 4: Identify and Remove Large Files

Identifying the largest files on your server can quickly free up space.

1. Utilize either WinDirStat or TreeSize to find the top 10 largest files.
2. Evaluate whether these files are necessary.
3. If not needed, delete or archive them to an external storage solution.

Conclusion

Freeing up disk space on Windows Server 2022 involves using built-in tools like Disk Cleanup, along with third-party applications such as WinDirStat and TreeSize Free. Regular maintenance and monitoring of disk usage will help prevent space issues in the future. Consider implementing a routine check to keep your server running smoothly and efficiently.
