The Blazor File Manager is a graphical user interface component for managing the file system that allows users to perform most common file operations like accessing, editing, and sorting files or folders. This component also provides easy navigation for browsing folders to select a file or folder from the file system.

Customizable layout design

The Blazor File Manager UI consists of toolbar, navigation pane, and content pane sections through which the files or folders in the file system can be accessed and managed. The complete layout can be customized with features like right-to-left alignment, enabling or disabling the toolbar and navigation pane, and switching between views.


The toolbar contains the list of tools for performing various operations like file upload or download and view switching. The toolbar can also be configured to add any custom functionality to be performed with the file system.
