The ent file extension is used for SGML entities.
In SGML and its derived markup languages HTML and XML, an entity is a named body of data associated with a document, or the unnamed document entity itself. Once defined, a named entity can be referenced any number of times within the document, via entity references.
An entity typically consists of a sequence of one or more characters, either encapsulated within a declaration of the entity's existence, or encoded and stored externally in a text file.
Such entities and their references are comparable to macros and include files in programming languages. However, entities don't necessarily have to contain parseable text; they may also be binary files that are included in a document only by reference, with the entity name as the value of an ENTITY-type attribute.
Use oXygen XML Editor to open *.ent files.
Use compatible tools to export *.ent files to other formats.

The ENT file extension is associated with AOL Instant Messenger, an instant-messaging client from AOL. The file stores various data used internally by AIM.
AIM was historically available for Microsoft Windows, Mac OS X, iOS and Android. The exact contents of an ENT file depend on the AIM component that created it, and the format was intended for use by the application rather than for manual editing.
AOL discontinued AIM, so the format is no longer actively maintained or generally used.
An ENT file is normally read automatically by the AIM installation that created it. It is not intended to be opened directly.
Because AOL discontinued AIM, a compatible installation may no longer be available. Do not edit or rename the file if it is part of an existing AIM installation.
ENT files contain internal AIM data rather than user documents and are not generally converted to another format.
If information from an old AIM installation is needed, recover it through the application or from a supported export or backup, where available.
