File Manager component in our Essential JavaScript 2

Introducing New JavaScript File Manager Control

We are happy to introduce the new File Manager control in our Essential JS 2 suite.

The File Manager component is a Windows-like file explorer that allows the end user to efficiently manage, browse, and upload files on the client-side of your web server.

The Essential JS 2 suite has a huge set of controls and those controls possess common web standards and functionalities such as web accessibility, right-to-left rendering, keyboard interaction, modular architecture, and responsiveness, with touch-friendly and lightweight UIs. Now the File Manager is included in this suite with all the common JS 2 features as well as control-specific features.

This blog will provide a walk-through on the new File Manager control, its UI designs, its available features, and the platforms it supports.

File Manager UI design

We designed the File Manager UI to be flexible and allow users to customize all its features. This is the design of the File Manager and a list of its interactive features.

Toolbar option

Toolbar at the top possesses all the action buttons to perform file managing operations: create, cut, copy, paste, upload, download, rename, and delete folders and files.

Left tree view for navigation

From the root file directory, the files are listed in tree structure (hierarchical structure) with expand and collapse options like in Windows File Explorer. This is used as a quick access to the files in the nested levels.

Quick access menu

This is a context menu option for performing operations on right-clicking over the files file data view.


Files and folders are shown in a details view or large icons view for quick management.

File access control

The File Manager provides methods to grant or restrict access rights to specific users and groups of users. You can define access permissions for folders and files using a set of access rules for them. By doing this, you can authorize people to read, write, delete, and upload files.

These access rules are validated on the server-side, so it will be more secure.

Sorting the files

You can sort the files and folder in the file system in either ascending or descending order by simply clicking on the column header. You can also sort files and folders based on name, date created, size, etc.
