DefaultFileProvider Class

File providers are components that provide APIs used to access and modify files and folders.

$("#file-manager").dxFileManager({
    name: "fileManager",
    fileProvider: new DevExpress.FileProviders.WebApi({
        endpointUrl: '@Url.RouteUrl("Default", new { controller = "api/FileManagerApi" })'
    }),
    height: 450
    //...
});

API Controller:

public IActionResult FileSystem(FileSystemCommand command, string arguments) {
    var config = new FileSystemConfiguration {
        Request = Request,
        FileSystemProvider = new DefaultFileProvider(_hostingEnvironment.ContentRootPath + "/wwwroot")
    };
    //...
}
