Windows 10 only provides simple disk file classification and statistics, which cannot meet our needs for more in-depth analysis and management of the file system. To further understand the disk space usage, we can use Disk Savvy, a third-party disk file analysis tool, to generate detailed and vivid disk file analysis reports on demand while analyzing the disk usage.
Tip: The free version of Disk Savvy provides basic disk file analysis statistics. There are also Professional, Flagship, Server, and Enterprise editions, all of which are paid versions that provide different levels of analysis services for server and enterprise storage systems.
First, start Disk Savvy software and add analysis targets. Click the + button in the middle Input column of the left pane of the software to add the partitions or directories to be analyzed, multiple partitions or directories can be added, and partitions and directories can be mixed. In addition, you can also add network share directories, server and NAS device directories, etc. (Figure 1).
After the target is added, click the first button Analyze on the toolbar to start analyzing the file situation at the target location. After the analysis, the results will be listed in three windows in different forms. The top right pane is sorted by the size or percentage of space occupied by files or folders, from largest to smallest; the bottom right pane, by default, is sorted by file extension category, also in the form of space occupied, from largest to smallest. The statistics pane on the lower left side shows the results of the current statistics, including the number of directories, files, space usage, statistical time, statistical efficiency, etc. (Figure 2).
The file categorization statistics method in the lower right pane is customizable. By clicking the triangle button in the category drop-down box, you can select the criteria for classifying files, such as statistics by file size, time or date the file was created, modified or accessed, file attributes, user name, etc. (Figure 3).
After the statistics are finished, you can output the file statistics analysis report. Click “Command→Save Analysis Report” command, in the pop-up report output customization box, select the report output file format and file name, and click the Save button to save the report. In the file format (Format), you can choose HTML, PDF, Excel, TXT, CSV and other formats (Figure 4).
If you wish to generate the report in a more visual chart format, click the Charts button on the toolbar and then select the type of analysis report chart from the drop-down menu to obtain a statistical report displayed as a pie chart (Figure 5).
