# Documents

*Last updated: May 12, 2026*

Use this path when your knowledge source starts as a file.

Direct file upload is not supported for formats like `TXT`, `PDF`, `DOC`, or `Excel`.

To use these files as assets, first add them through Google Drive.

### Add document files through Google Drive

Follow these steps:

1. upload them to Google Drive
2. share them with **<support@aissistant.io>** or set them to **Anyone with the link can view**
3. add them through the Google Drive asset flow

For setup steps, see [Google Drive](/tutorial/turn-assets-into-ai/google-drive.md).

### Best practice

Use Google Docs or Google Sheets when possible.

Use uploaded files when the source already exists in another format.
