# Search Dropbox in your knowledge base with Duaer

Connect Dropbox to the Duaer knowledge base. People ask about files in shared folders, and find only what Dropbox shares with them.
## What does Duaer find in Dropbox?

Duaer indexes up to 5,000 files the connected account sees: its own folders and the shared folders it belongs to. PDF, Word, Excel, PowerPoint, text, Markdown, CSV and JSON files up to 20 MB are read; other files are found by name.

People can ask “How is the Nordics pipeline doing?”. Duaer finds the answer in a file in a shared folder and cites it, and the citation opens the file in Dropbox.

## How do you connect Dropbox to Duaer?

1. In Duaer, create a Dropbox OAuth2 API credential with full Dropbox access and authorize it with a Dropbox account that is a member of the shared folders people should search, or use a Dropbox API credential with an access token.
2. As an owner or admin, open Knowledge base › Data sources, choose the credential on the Dropbox card and click Connect.
3. When indexing is done, ask a question whose answer is in a Dropbox file and check that the citation points to that file.

## Who finds which file?

- A file in a shared folder: that folder's members.
- A file shared on its own: its members as well.
- A link open to the team or to anyone: the whole Duaer organization; files open to anyone are also marked public for the sensitive content check. Password and members-only links do not count.
- A file shared with nobody: the connected account only.

Members are matched to Dropbox users by email. When a file is shared with a Dropbox group, its members cannot be read yet, and the source card counts the items this affects.

## What are the limits?

- Only what the connected account sees: other members' private folders that are not shared with it are not read. To cover the team, connect the account that belongs to the most shared folders.
- Up to 5,000 files; files over 20 MB or in other formats are found by name only; Paper docs' content, file versions and comments are not read.
