"发送文件清单" can be translated into English as "List of Files Sent" or "File Transmission List".
"List of Files Sent" directly conveys the idea of a list detailing the files that have been dispatched or transmitted.
"File Transmission List" emphasizes the act of transmission and the list that documents it, which might be more appropriate in contexts where the focus is on the process of sending files.
Both translations are accurate and can be used depending on the specific context and emphasis.
