　　Thank myang offer this information.

Backup any critical data in the guest OS.

Download Eraser, (http://www.tolvanen.com/eraser/) and install it in the guest OS. Alternative disk 'zeroing' software can also be used.

Defragment the guest OS hard drive.

Run Eraser in the guest OS.

Click Edit, then Preferences, then Erasing

Select Unused Disk Space

Select New

Enter the description Blank

Click Add

Create a 3-byte pattern of zeros

Click Save

Select Blank under Unused disk space

Click OK.

Click File, then New Task

Select Unused space on drive

Select Local Hard Drives

Click OK

Select Task, then Run on the previously created task

Wait for completion

Close the report

Exit Eraser and shutdown the guest PC.

Use Virtual Disk Wizard on the Host PC to reclaim lost space. Click File, then Virtual Disk Wizard.

Click Next to start the wizard.

Select Examine or modify existing disk and click Next.

Click Browse to locate the disk image, double-click the image file and click Next to continue.

Select Compact the Disk image and click Next.

Virtual PC allows the use of a secondary file to compact the disk. It's a good idea to have the image file be compacted to a new file and then verified to prevent data loss or corruption of the original image file. Select New File, browse or enter a new location, click Next to continue.

Click Finish to start the process. When finished, click Close.
