Document list within a knowledge base datasource ## Viewing documents Navigate to a knowledge base and click on a datasource to see its documents. Each entry shows: * **Filename** — The uploaded or synced document name * **Status** — Processing state (Uploaded, Processing, Indexed, Failed) * **Date added** — When the document was uploaded or synced * **Size** — File size ## Uploading new documents To add documents to an existing file-upload datasource: 1. Open the knowledge base and select the datasource 2. Click **Upload Files** or drag and drop new files 3. Wait for processing to complete New documents are indexed independently — adding files does not re-index existing ones. ## Removing documents 1. Open the knowledge base and navigate to the document 2. Click the **Delete** action 3. Confirm the deletion Removing a document deletes it from storage and removes its chunks from the vector index. Agents will no longer cite content from that document. ## Replacing documents To replace an outdated document: 1. Delete the old document 2. Upload the new version There is no in-place update — remove and re-upload to ensure the document is fully re-processed and re-indexed. ## Bulk operations For SharePoint or Google Drive datasources, document management is handled automatically by the sync process. Neural Factory detects additions, updates, and deletions during each sync cycle. This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
