Manage files

Upload, store, and manage files in Langflow's File management system.

Uploading files to the File management system keeps your files in a central location, and allows you to re-use files across flows without repeated manual uploads.

Upload a file​

The File management system is available at the /files URL. For example, if you're running Langflow at the default http://localhost:7860 address, the File management system is located at http://localhost:7860/files.

To upload a file from your local machine:

  1. From the My Files window at http://localhost:7860/files, click Upload.
  2. Select the file to upload. The file is uploaded to Langflow.

You can upload multiple files in a single action. Files are available to flows stored in different projects.

Files stored in My Files can be renamed, downloaded, duplicated, or deleted.

To delete a file from your project, hover over a file's icon to click and select it, and then click Delete. You can delete multiple files in a single action.

To download a file from your project, hover over a file's icon to click and select it, and then click Download. You can download multiple files in a single action, but they will be saved together in a .ZIP file.

Use uploaded files in a flow​

To use your uploaded files in flows:

  1. Include the File component in a flow.
  2. To select a document to load, in the File component, click the Select files button.
  3. Select a file to upload, and then click Select file. The loaded file name appears in the component.

For an example of using the File component in a flow, see the Document QA tutorial project.

note

If you prefer a one-time upload, the File component still allows one-time uploads directly from your local machine.

Send files to a flow with the Langflow API​

For information on file management with the Langflow API, see Files endpoints.
