File association
open-in-new
<p>In <a href="/facts/Computing/Kghtm9fX">computing</a>, a file association associates a file with an <a href="/facts/Application_software/YQuj7Kog">application</a> capable of opening that file. More commonly, a file association associates a class of files (usually determined by their <a href="/facts/Filename_extension/cJgfAym4">filename extension</a>, such as <a href="/facts/.txt/zYW4JmES">.txt</a>) with a corresponding application (such as a <a href="/facts/Text_editor/jPCgtbvN">text editor</a>). </p>
