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 ## Replacing documents To replace an outdated document: 1.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.
