Another powerful capability is the ability to display the disk space usage timeline charts for all analyzed files or filtered file classification results.
In the simplest case, press the 'Charts' button located on the main toolbar and select the 'Disk Space Usage Per Modification Year' menu item.
DiskSavvy will display a time line chart showing how much data was modified per year. In order to display how many files were modified per year,
set the chart mode to 'Number Of Files Per Modification Year'. In addition, the user is provided with the ability to display timeline charts
for filtered disk space analysis results.
For example, in order to display how many documents were created per year, set the file categorization mode to 'Categorize By File Type', select the 'Documents, Books and Help Files' file
category, press the right mouse button and select the 'Apply Selected Filters' menu item. Now, with the file filter active, press the 'Charts' button
located on the main toolbar, and select the 'Disk Space Usage Per Creation Year' menu item.
One of the easiest ways to assess how much of the used disk space can be freed by archiving old, unused files is to display the last access year timeline chart. The timeline chart shows
how much disk space is used by files which were last accessed during the last 15 years allowing one to easily identify the proportion of recently accessed files and old, unused files.
In order to identify which time of the day is the best time to perform backup operations, the user can display the 'Number of Files Per Creation Hour' or 'Number of Files Per Modification Hour' timeline charts.
The 24-hours timeline chart shows how much disk space and how many files were created or modified during each hour of the day allowing one to easily select the time for backup operations. In order to save, a time line chart, press the 'Save' button, select an appropriate chart format, enter a file name and press the 'Save' button.
