I have a program requesting to rename the downloaded folder, so I found the following code on the Internet:

Header ("Content-type: application/octet-stream ");
Header ("Accept-Ranges: bytes ");
Header ("Content-Type: application/force-download ");
Header ("Content-Disposition: inline; filename =". $ filename );
Header ("Accept-Length:". filesize ($ File ));
@ Readfile ($ File); // read the File to the output cache


However, when downloading a file, only the number of opened files is displayed... The download progress is not displayed.
