The difference between "The file has been sent" and "We have sent the file" is mainly in their passive and active voice constructions: "The file has been sent" is in the passive voice. It emphasizes that the action of sending the file has been completed, but it doesn't specify who sent it. This construction is often used when the focus is on the status of the file being sent. "We have sent the file" is in the active voice. It specifies the subject ("we") who performed the action of sending the file. This construction is used when you want to emphasize who took the action of sending the file. So, the choice between these two phrases depends on whether you want to highlight the action itself ("The file has been sent") or the doer of the action ("We have sent the file").
