Vopt9 release notes

This document describes the latest changes in Vopt 9.

Changes from 9.02 to 9.04

Vista - Added code to work around a Vista SP1 error (i.e. "design feature") which prevents defragmenters from moving files larger than 4GB without locking up. If using Vista-- even with this work-around--defragmenting or moving a file larger than 4GB while the drive is being written to by other applications, may fragment the file.

Vista/Windows 2003 - Added "VSS compatible Defrag" command. If Volume Shadow Copy is enabled on Vista or Windows 2003 Server volumes having a cluster size of less than 16KB, normal defragmenting may result in the loss of system restore points if there is insufficient space allocated for system restore. "VSS compatible Defrag" minimizes the number of files moved and the total size of files moved. Files larger than 64 MB are not moved or defragmented. File packing is minimal.

New logic for "Defrag pagefile" command to minimize system restore increase.

Corrected a problem which prevents Analyze/Defrag from running on some systems.

Minor improvements and problem corrections. Minor cosmetic changes.

Changes from 9.0 to 9.02

Added Hungarian translation.

Accounted for drives with unknown bus type in drive failure prediction routine.

Corrected internal consistency checks which were causing erroneous error reports.

Corrected initial display error on systems with FAT32 boot drives.

Corrected minor errors.

Changes from 8.18 to 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 .
