What is an ANN file?

ANN files are only used to describe Lingvo-formatted dictionaries. This format is developed by ABBYY, an international software company. ANN files are optional, but if they are created, they are named after an associated .DSL file (e.g., example.dsl and example.ann). ANN files should be placed in the same folder as the DSL file.
NOTE: You can view the information in an ANN file by double-clicking the icon of the dictionary located on the Bookshelf in Lingvo Dictionary.

Microsoft introduced WinHelp in Windows 3.0 in 1990 to allow users to look up help documentation about the operating system and related applications. Microsoft replaced WinHelp with Windows Help in 2009, then discontinued the software in 2015 when it released Windows 10.
When viewing a help document in Windows Help, you can add extra information to the documentation that you find helpful. When you create the annotation, Windows Help saves the information in the ANN file.
