Running out of space on your Windows 11 virtual machine (VM)? Whether you need more room for files, software, or general storage, expanding your VM’s disk is easier than you think.
This guide covers:
✅ How to add disk space in VMware Workstation Pro

✅ Best free tool to analyze disk usage (TreeSize Free)
📌 Prerequisites
Before starting, ensure you have:
✔ VMware Workstation Pro (now free for personal use)
✔ Administrator access to your Windows 11 VM
✔ Backup of important data (optional but recommended)
🛠️ Step 1: Expand the Virtual Disk in VMware
1. Shut Down the VM
- Close all programs and power off the Windows 11 VM.
2. Open VMware Workstation Pro
- Select your VM → Right-click → Settings.
3. Increase Disk Size
- Go to Hard Disk (SCSI).
- Click “Expand” and enter the new size (e.g., add 25GB).
- Remove snapshots if prompted (they block disk expansion).
4. Apply Changes & Restart
- Click OK → Wait for the process to complete.
- Power on the VM (new space won’t appear yet).
💽 Step 2: Extend the Partition in Windows Disk Management
1. Open Disk Management
- Press
Win + X→ Select “Disk Management”. - You’ll see unallocated space (but it may not be usable yet).
2. Fix Unallocated Space Issue
If the new space appears after the recovery partition, Windows can’t extend the main volume.
Solution: Delete Recovery Partition (Optional)
- Open Command Prompt as Admin.
- Run:
diskpart
list volume
select volume X (Replace X with recovery partition number)
delete volume
exit- Rescan disks in Disk Management.
3. Extend the Main Partition
- Right-click C: drive → Extend Volume.
- Follow the wizard → Use all available space.
🔍 Step 3: Analyze Disk Usage (Optional)
If you can’t expand the disk, clean up unnecessary files using:

⚡ Pro Tips for Managing VM Disk Space
✔ Use dynamic disks (allocates space as needed).
✔ Regularly clean temp files (%temp%).
✔ Move large files to an external drive.
✔ Defragment the VM disk (if using HDD).
⚠️ Important Notes & Troubleshooting
❌ Snapshots prevent disk expansion (delete them first).
❌ Recovery partitions block extension (delete via DiskPart).
❌ Dynamic disks can’t shrink (only fixed-size disks).
