# Disable Filtering or Extraction for Specific Documents

To prevent File Content Extraction from processing specific documents, you can add the following fields to documents. You can add the fields with any value.

AUTN_FILTER_META_ONLY | Prevents CFS extracting content from a file. CFS only extracts metadata and adds this information to the document.
AUTN_NO_FILTER | Prevents CFS extracting any text (metadata or content) from a file. This can be useful if you do not want to extract text from certain file types.
AUTN_NO_EXTRACT | Prevents CFS from extracting sub-files. This can be useful if you want to avoid extracting items from ZIP files and other container files.

NOTE: To add a field to a document, use a Lua script. You must run the Lua script using a Pre import task. This is because Post import tasks run after File Content Extraction filtering.
