Abstract

The invention discloses a method for uploading and downloading a file offline by a terminal. The method comprises the steps of uploading and downloading the file, creating a file uploading and downloading task, processing the file uploading and downloading task, and uploading or downloading the file in a file library after a file cloud receives the file uploading and downloading task. According to the method, local uploading and downloading tasks can be stored under the condition that no network exists, connection with a target system or a server is established after the network is connected, and automatic retransmission is carried out. According to the method, a user can directly finish uploading and downloading operations on all files on a terminal application (a user center).
