- Show/Hide hidden items
- Show/Hide thumbnail images in large icons view
- Toolbar customization
- Upload customization

Context menu customization
The context menu settings like, items to be displayed on files, folders and layout click and visibility can be customized using contextMenuSettings property.
@{
string[] files = new string[] { "Open", "|", "Details" };
string[] folder = new string[] { "Open", "|", "Details" };
string[] layout = new string[] { "SortBy", "View", "Refresh", "|", "Details" };
}

Show/Hide file extension
The file extensions are displayed in the File Manager by default. This can be hidden by disabling the showFileExtension property.
In File Manager fileLoad and fileOpen events are triggered before the file/folder is rendered and before the file/folder is opened respectively. These events can be utilized to perform operations before a file/folder is rendered or opened.
