TreeSize uses the MTP (Media Transfer Protocol) to access data on mobile devices. By now, MTP is the only generic way to access data on Android and IOS devices.

With MTP, the device itself keeps full control over which data are available and which are not. System files and other critical data usually remain hidden this way.

The free space of a drive - as well as its capacity - is a fix information and is not applicable for single files or folders.

Both of these informations are shown in the status bar after scanning a drive.

The free space can also be included with the treemap chart. The according option can be found on the contextual ribbon tab after activating the chart.

The percent values in TreeSize are defined to be based on the accessible and filtered sizes - so basically to the size values also shown in the related columns (depending on the current view mode: size, allocated space, or number of files).

Using the capacity of a drive instead would break this definition and even be undefined for many usecases (What's the number of unused files on a drive? How to interprete filtered results? How to calculate the capacity of a subfolder? ...)

The capacity and free space of a drive are represented as their own piece of information in the statusbar instead and can be shown as a separate tile with the treemap chart instead.
