All information presented in the main dialog is organized in two panels: Tree panel and List panel.
Tree panel displays an active partition with its brief description as Tree root and File system virtual directory indicating file system status. File system directory contains folders available from your computer without scanning. Any scan results will appear as Tree virtual directories under File system directory after partition scanning.
If a directory is expandable there appears a right-arrow sign next to a selected directory.
To expand a directory click the right-arrow sign. To collapse a node press drop-down arrow sign.
List panel displays folders and files contained in an active directory after opening it. Folders and files are sorted by file names in descending order starting with folders.
