The File Explorer component displays a filesystem tree to the user. It can be rooted at any folder, even network folders. It can also filter the types of files that are displayed by their file extension (i.e., "pdf"). The path to the file that the user selects in the tree is exposed in the bindable property Selected Path.
The File Explorer component is typically used in conjunction with the PDF Viewer component in order to create a PDF viewing window. This is very useful for viewing manuals, documents, or reports from within your project. To use this component to drive a PDF Viewer component, refer to the section on File Explorer and PDF Viewer.
