  • Sortable Columns in Bar Chart and My Computer Report - data in the bar chart report can now be sorted by clicking on column headers in the bar chart and 'My Computer' reports.

Bug Fixes :

  • Disk Usage Report for Current Folder in Visualizer- If DiskView Visualizer was closed and re-opened after navigating to another folder, it did not always sync up with the new folder and required a manual navigation step. This has been resolved in the current version.
  • Focus Traversal and Keyboard navigation - Keyboard navigation in the Folders pane when the Visualizer was open was interrupted due to loss of focus in certain cases. This has now been resolved for all use cases.
  • Advanced Options tab of DiskView Options dialog is greyed out in DiskView trial edition, as it is only applicable for DiskView Professional Edition, and does not work in Trial and Standard versions of DiskView.
  • Blank report was shown in the Visualizer on certain occasions if scan warnings were enabled. This bug has been resolved.
  • Trailing slash (/) in folder path is now handled correctly by DiskView FSInfo component

Changes :

  • File Fragmentation report has been turned on by default.
  • Pie labeling - Pies are labeled when size of the file or folder they represent is more than 2% of the size of their parent folder. Earlier this percentage was 5% by default.
  • Compressed files and folders are shown in blue color similar to Windows Explorer. Earlier a zip icon was used to represent them leading to cluttered display on compressed drives and folders.

DiskView 1.1

Vyooh, the emerging software leader in data analysis, visualization and management announces the release of DiskView v 1.1. This release features enhancements that enable automatic scheduling of DiskView Analyzer, faster startup time and provides increased control of Explorer integration. In addition to the enhancements, this release also contains bug-fixes further enhancing performance, quality and stability.


  • DiskView Analyzer can be scheduled using Windows Task Scheduler.

    DiskViewAnalyzer.exe takes an optional command line parameter " -auto" that causes it to run a background scan. By scheduling a task in the "Scheduled Tasks" available from the Control Panel, and setting ' "C:\Program Files\Vyooh\DiskView\DiskViewAnalyzer.exe" -auto ' as the program to be run, the scan can be scheduled to run daily, weekly, monthly, or when the computer is idle.
    Another easy way to set up the scheduled task is by copying this job file to the ' Control Panel > Scheduled Tasks' folder. Then just right click, specify the user password, and modify the task schedule to run the Analyzer on a regular basic, or when the computer is idle.
  • Explorer Integration Options have been added to the "More Options" tab of DiskView Options dialog. The integration options can control:
    • If Explorer should be started after Disk Analysis is complete
    • If the Visualizer panel should be auto-started with Explorer (this can cause Visualizer to take up the whole bottom part of Explorer, as opposed to the bottom right corner)

  • Faster startup time. DiskView startup speed should improve from 50-200% due to an optimization and a related bug-fix.

Installation Notes:
All existing customers are eligible for free upgrades. Existing DiskView keys will work with this upgrade, without requiring users to register again. The previous version of DiskView should be uninstalled before running the version 1.1 installer.
