Create a File Manager

The following code creates the FileManager widget and adds it to your page.

jQuery
index.js
index.html
data.js
$(function () {
    $("#file-manager").dxFileManager({
        fileProvider: fileSystem,
        currentPath: "Documents",
        height: 450,
        permissions: {
            create: true,
            copy: true,
            move: true,
            remove: true,
            rename: true
        }
    });
});
<div id="file-manager"></div>
var fileSystem = [
    {
        name: "Documents",
        isDirectory: true,
        items: [
            {
                name: "Projects",
                isDirectory: true,
                items: [
                    {
                        name: "About.rtf",
                        isDirectory: false,
                        size: 1024
                    },
                    {
                        name: "Passwords.rtf",
                        isDirectory: false,
                        size: 2048
                    }
                ]
            },
            {
                name: "About.xml",
                isDirectory: false,
                size: 1024
            },
            {
                name: "Managers.rtf",
                isDirectory: false,
                size: 2048
            },
            {
                name: "ToDo.txt",
                isDirectory: false,
                size: 3072
            }
        ],
    },
    // ...
];

Bind the File Manager Widget to a File System

Create a file provider that allows you to access and modify file systems.

NOTE
In this section, the Object file system is used to quickly bind the FileManager widget to data. Refer to the Bind to File Systems section for more information on supported file systems.

To bind the FileManager widget to a hierarchical data structure, create an Array file provider and assign the array of hierarchical JSON objects to the provider's data option. The Array file provider automatically binds data objects to the widget if the data objects have the default 'name', 'size', 'dateModified', etc., fields in their structure. For example:

var fileSystem = [
{
    name: "MyFile.jpg",
    size: 1024,
    dateModified: "2019/05/08",
    thumbnail: "/thumbnails/images/jpeg.ico",
    isDirectory: true,
    items: [
        // ...
        // Nested data objects with the same structure
        // ...
    ]
    // ...
}];

In the example below, the FileManager widget displays hierarchical data stored in an in-memory array that contains fields with conventional names:

jQuery
index.js
data.js
$(function() {
    $("#file-manager").dxFileManager({            
        fileProvider: fileSystem,
        // ...
    });
});
var fileSystem = [
    {
        name: "Documents",
        isDirectory: true,
        items: [
            {
                name: "Projects",
                isDirectory: true,
                items: [
                    {
                        name: "About.rtf",
                        isDirectory: false,
                        size: 1024
                    },
                    {
                        name: "Passwords.rtf",
                        isDirectory: false,
                        size: 2048
                    }
                ]
            },
            {
                name: "About.xml",
                isDirectory: false,
                size: 1024
            },
            {
                name: "Managers.rtf",
                isDirectory: false,
                size: 2048
            },
            {
                name: "ToDo.txt",
                isDirectory: false,
                size: 3072
            }
        ],
    },
    //...
];
