ICA files are configuration files used by Citrix systems to connect to remote applications or desktops. These files contain instructions for the Citrix Receiver or Citrix Workspace app, specifying the server address, application details, and connection settings necessary to establish a remote session. Double-clicking one of these files typically launches the appropriate Citrix client and initiates the connection process as outlined within the file.
The utilization of these files streamlines access to virtualized environments. They provide a standardized and convenient method for distributing connection parameters to users, ensuring consistent and secure remote access. Historically, ICA files have been instrumental in enabling organizations to deliver applications and desktops to a diverse user base regardless of location or device.
