718* The path you specify is rooted under the session's uploads directory: a `mount_path` (java, php: `mountPath`; csharp, go: `MountPath`) of `/data.csv` places the file at `/mnt/session/uploads/data.csv` in the sandbox
719* If you omit `mount_path` (java, php: `mountPath`; csharp, go: `MountPath`), the file is placed at `/mnt/session/uploads/<file_id>`
720* Parent directories are created automatically
