An ICA file is an Independent Computing Architecture (ICA) file used by Citrix application servers. It contains configuration information for connecting to different servers and may link to a published application or to a server desktop environment. ICA files can be created with the ICA File Creator program or a basic text editor.
ICA files allow users to connect to remote virtual desktops so the user's computer does not need the applications to be installed locally. This mechanism provides advantages for system administration and also allows users to access critical business applications, or "enterprise applications," from remote locations.
