# Upload file

> Uploads a file to the device via multipart form data, writing it into the directory given by the path query parameter using the uploaded file's name.

`path` is the destination **directory**, not the full file path — the file is written there under its original uploaded filename. Paths are rooted at the device's shared storage (`/` is the storage root): uploading `report.pdf` with `path=/Download` creates `/Download/report.pdf`.

<Tip>
  File access runs without root and stays within the device's shared storage tree; protected system paths are not reachable.
