# History

In the History view you can see line charts visualizing the size development of the selected root folder.

After each scan the size, allocated space, and number of files of the root folder are stored automatically in an XML file in the users profile of the currently logged-in user.

These sizes are used to create this view. As a result the shown interval and frequency depends on the scans you have performed for this root before.

Note

By default, only scans of the same path and the same exclude filters will be displayed in the history, since a common base is needed to compare scans. Using the Ignore scan filter option allows to include scans of the same path, but with differing exclude filters.
