Disks Tab (Pro version only)
Erasing disk free space ensures that any data currently stored in unallocated space in your hard disk will be obliterated. Any tracks that may be left over from deleted files will be destroyed. This function is useful if you have deleted some files in Windows explorer and you want to ensure those files will not be recovered by any recovery tools.
If you directly delete files in Windows explorer, the data in the deleted files will not be actually removed from your hard disk. This function will let you permanently remove all the data on the free space on your hard disk.
Notes:
- The operation may take a long time to run if you have large free disk space on your hard disk.
- Under Windows XP and Windows ME, this operation may cause the System Restore feature to discard all of your existing Restore Points, and create a new Restore Point after it is completed.
- This function allocates all available free space on the selected drive. Therefore, it is normal for Windows to present a warning prompt that you have run out of disk space while it is working. Some versions of Windows may offer to launch the Disk Cleanup utility for you. If this prompt appears (and it may appear more than once), just close it and do not launch the Disk Cleanup utility.

To start to erase the free disk space, please select the disk drive you want to erase and click the "Erase" button. |
