Why is my Azure Virtual Machine's disk space quickly getting full and how can I resolve this issue?

Disk space is used as new files are created. On a virtual machine, the culprits are commonly log files (either in number or in size), application installations, or large archives like VM images/backups.

You can remove files and applications that aren't needed, archive data that isn't immediately necessary, add storage to your VM, monitor disk use, and create policies to reduce log file growth.

Find large files and folders:

Check for large files and folders consuming disk space. You can use disk space manager tools to identify large files and directories.

  Investigate log files, temporary files, or application data that may be growing unexpectedly.
  
  **Clean Up Disk Space**:
  
     Delete unnecessary files and temporary data. You can use built-in utilities like [Disk Cleanup](https://support.microsoft.com/en-us/windows/disk-cleanup-in-windows-8a96ff42-5751-39ad-23d6-434b4d5b9a68).
     
        Compress or archive log files that are not needed immediately.
        
           Uninstall applications you no longer need.
           
           **Monitor Disk Usage**:
           
              Set up monitoring and alerts for disk space usage to proactively manage and avoid similar issues in the future.
              
                 Use Azure Monitor to track disk space metrics and configure alerts to notify you when disk usage exceeds a certain threshold.
                 
                 **Optimize Storage**:
                 
                    Consider [resizing your disk](https://learn.microsoft.com/en-us/azure/virtual-machines/windows/expand-os-disk) if the current size is insufficient for your needs. Azure allows you to increase the disk size without downtime.
                    
                       [Attach a managed data disk](https://learn.microsoft.com/en-us/azure/virtual-machines/windows/attach-managed-disk-portal) to store files and data.
                       
                          Implement data retention policies to manage the growth of log files and other data systematically.
