The UI component's default security settings provide read-only access to files and directories. Use the permissions property to deny or allow a user to copy, create, move, delete, rename, upload, and download files and directories. You can also specify file restrictions: allowed file extensions (allowedFileExtensions), chunk size (chunkSize) and maximum file size (maxFileSize).
Use the UI component's itemView property or the view switcher on the toolbar to display file system items as a detailed list or customizable thumbnails.
This demo contains commented out code lines that enable file modification operations. You can uncomment them and configure if necessary.
