AN file format:

To view or edit AN files you need to know the file format, because it determines how the data in this file is stored. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions.
