# What file types will Nightfall scan for sensitive data? What are the limitations?

Nightfall scans for sensitive data in a broad range of file types

Nightfall supports scanning most file types, except for audio and video files.  Image files are scanned using optical character recognition (OCR). Embedded files images and non-visible URLs are included in file scans. Max file size is **1 GB.** Contact us at <support@nightfall.ai>, if you need us to raise this limit.&#x20;

* Google Workspace documents (Doc, Sheet, Slide, etc.)
* Image file types (PNG, JPG, TIFF, GIF, etc.)&#x20;
* PDF files
* All text-based document files (HTML, TXT, etc.)&#x20;
* All text-based code and config file types
* All text-based data file types (CSV, TSV, JSON, XML, parquet, etc.)
* Compressed file types (zip, gzip, etc.) are decompressed, and the contained files are scanned.&#x20;

**Unsupported file types** (audio, video, and animation):

* audio/midi
* audio/mpeg

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://help.nightfall.ai/detection_platform/faq/file_types_scanned.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
