WCX File – What is .wcx file and how to open it?

.WCX File Format

A .WCX file, or RemoteApp and Desktop Connections Configuration File, is created upon the initial setup of a Remote Desktop Services (RDS) deployment. This XML-based file contains the configuration settings for RemoteApp and Desktop Connection (RDC) clients, which are used to establish connections to remote applications and desktops hosted on an RDS server.

Contents and Purpose

The .WCX file serves as a central repository for client-side configuration parameters that define the behavior of RDC clients. It typically includes information such as the hostname or IP address of the RDS server, the authentication method (NTLM, Kerberos, etc.), security settings (encryption level, SSL certificate validation), and display settings (resolution, color depth). Additionally, the file may specify application bindings for RemoteApp connections, allowing users to launch specific applications remotely without having to explicitly connect to a remote desktop.

Deployment and Usage

.WCX files are typically distributed to client devices through various methods such as email, network shares, or Group Policy. Once deployed, the file can be imported into the RDC client using the Import Connection Settings feature. Importing the .WCX file simplifies and streamlines the client configuration process and ensures that all necessary settings are applied consistently across devices. This is particularly beneficial in environments where multiple RDC clients need to be configured to connect to the same RDS deployment.

Using the File Association:

WCX files are primarily associated with the Remote Desktop Connection (RDC) feature in Windows operating systems. To open a WCX file, simply double-click on it in Windows Explorer or File Explorer. This will automatically launch the RDC client application, which will load and establish the remote connection specified in the WCX file. If you encounter any issues, you can manually launch the RDC client application and open the WCX file through the File menu within the application.

Using the Command Line:

Alternatively, you can open a WCX file using the command line. Open a Command Prompt or PowerShell window and navigate to the directory where the WCX file is located. Type the following command, replacing “myfile.wcx” with the actual filename:


mstsc /v myfile.wcx


This command will launch the RDC client application and automatically load the remote connection configuration specified in the WCX file. Ensure that you have sufficient permissions to execute this command.

What is a WCX File?

A WCX file, short for RemoteApp and Desktop Connections Configuration File, stores connection settings for accessing remote desktop and application environments. It contains information such as the IP address or domain name of the remote server, the user’s credentials, and any custom configuration settings. WCX files enable users to quickly establish connections to remote resources without having to manually enter details each time.

Usage and Benefits

WCX files are primarily used in conjunction with Microsoft Remote Desktop Services, which provides remote access capabilities to virtualized desktops and applications. When a user creates a new remote connection, they can save the configuration settings as a WCX file. This file can then be imported into other devices or shared with other users who need to access the same remote resources. By using WCX files, organizations can streamline the process of connecting to remote environments, improve security by standardizing connection settings, and simplify remote access management.
