· Fast - When used regularly, it finishes in a few minutes.
· Safe - Your disk data is fully protected.
· Easy - You can choose manual or automatic defragmentation--daily or weekly.

Changes in version 9.0 :
- Doubled maximum partition size to 16 TB (when formatted normally with 4096 byte clusters). For drives formatted with 512 byte clusters (very inefficient!) the maximum is increased to 2 TB.
- Added drag and drop.for moving individual files to new disk locations from any of the "Clusters" or "Usage" windows. Note that this can be used to defragment single files.
- Improved defragmentation and packing engines.
- Faster free space erase (3X).
- Added "Usage" mini-map to status line.
- Added "Drive failure prediction" and "Drive performance" functions.
- Added "Usn journal mangement" function. The $UsnJrnl metafiles are a database created by the Indexing and Windows Messenger services. $UsnJrnl can become very large and fragmented and cannot be moved or defragmented.
- Added "System information" link.
- Added "Trash" to "Status" menu display if.system dump files are detected.
- Added "System information" link.
- Added new menus to make Vopt's (apparently less used or known) features more accessible. The new Usage menu provides direct access for examining the excluded, fixed, fragmented files, etc.
- Map colors now shown for MFT, Pagefile, and hiberfile on initial drive selection (pre-analyze).
- Added map color for excluded files. Files can now be excluded from the right-click popup menu in any of the "Clusters" or "Usage" windows.
- Added map color for prefetch files. Prefetch files are the boot and application startup files which are tracked in the Layout.ini file. These are automatically repositioned every three days by Windows.
- Sundry improvements and fixes .

Supported Windows 2000, 2003, XP and Vista.
