DiskBoss provides advanced disk space utilization analysis capabilities allowing one to analyze one or more local disks, network shares or NAS storage devices and easily identify directories and files holding significant amounts of the disk space.

The user is provided with the ability to browse files and directories sorted by the used disk space, filter analysis results by the file extension, category, file size, last access time, user name, etc. and easily identify disk space usage hotspots. In addition, DiskBoss allows one to perform file management operations on analysis results, generate various types of disk space analysis charts and export reports into a number of standard formats such as HTML, XML, Excel CSV and ASCII text.

The top view of the analysis results dialog shows directories and files sorted by the amount of the used disk space and the bottom view shows the currently selected file categories, which are allowing one to categorize and filter files and directories displayed in the top view. In order to apply one or more file categories as a filter, select the required file categories in the bottom view, press the right mouse button and select the 'Apply Selected Filters' menu item. DiskBoss will filter the disk space analysis results and display in the top view files matching the selected file filters and directories containing these files.

With an active file filter, all operations such as browsing, file copy, move and delete, reports generation, charts, etc. will be performed on filtered results only. In order to reset the currently active file filter, press the right mouse button over the filters view and select the 'Clear Selected Filters' menu item.

DiskBoss provides numerous types of charts capable of displaying the used disk space per directory, file category, extension, file size, last access, modification and creation times, etc. In order to open the charts dialog, just press the 'Charts' button located on the results dialog's toolbar. By default, the charts dialog shows the amount of the used disk space per directory for the currently displayed file system location. In addition, the chart mode selector allows one to show the number of files per directory, the used disk space per category and the number of files per category.

DiskBoss allows one to copy, move and delete files and directories displayed in the disk space analysis results dialog. In order to perform a file operation on one or more files or directories, select the required items in the directory view, press the right mouse button and select an appropriate file operation.

DiskBoss allows one to save disk space analysis results into a number of standard formats such as HTML, XML, text and Excel CSV. In addition, the user is provided with the ability to save results to the DiskBoss' native report format, which is capable of preserving all information related to each specific disk space analysis operation and may be loaded at any time just by clicking on a report file in the DiskBoss' file navigator.

One of the most powerful analysis capabilities provided by DiskBoss is the integration between disk space analysis and file search features allowing one to perform disk space analysis on files matching one or more user-specified rules. For example, the user is provided with the ability to analyze files related to a specific file category, with a specific file size that were modified or created during a specific time period or any other combination of user-specific rules.

The DiskBoss' disk space analyzer provides the ability to combine disk space analysis operations with file classification capabilities allowing one to precisely understand what types of files are stored in directories holding most of the disk space. In order to classify files in one or more directories displayed in the disk space analysis results dialog, select the required directories in the directory view, press the right mouse button and select the 'Classify Files' menu item. On the 'Classification Plugins' dialog selected an appropriate file classification plugin and press the 'Classify' button.

The file classification results dialog shows file categories and classes according to the selected file classification plugin and provides the user with the ability to export charts, save reports, submit results to an SQL database, perform file management operations on specific file types and physically reorganize files on the disk. Moreover, the user is provided with the ability to apply second-level file categories and filters by the file size, extension, last access, creation and modification dates, etc. to further focus on specific files or file groups.

DiskBoss Ultimate and DiskBoss Server provide the ability to save disk space analysis reports into an SQL database. A long-term history of disk space analysis reports from multiple servers and desktop computers may be submitted to a centralized SQL database and used to analyze disk usage trends across the entire enterprise.

Finally, IT and storage administrators are provided with the ability to analyze disk space usage reports from multiple servers or desktop computers and display the used disk space and the number of files per user and/or per host allowing one to gain an in-depth visibility into disk space usage patterns across the entire enterprise.
