# Filter HTML Files

KeyView can filter comments from HTML documents. To enable comment filtering, you must set a flag in the `formats.ini` file.

The `formats.ini` file is in the `install\OS\bin` directory, where `install` is the Filter installation directory and `OS` is the name of the operating system.

To enable filtering of comments from HTML files

1. Open the `formats.ini` file in a text editor.

2. Under `[Options]`, set the following flag.
