Choose Window > Downloads to view the list of downloaded files. Then:
Check to see if the file is still being downloaded.
See if downloading has been paused. If you see the Resume button (orange with a curved arrow) next to the file’s name, click it.
If the file has been downloaded but you can’t find it, click the magnifying glass beside the file’s name. If you moved the file after it was downloaded, Safari won’t be able to find it.
If you can’t open the file, you may not have an application that opens it. Check the site where you downloaded the file for more information.
If you can’t open the file with the application that created it, the file may have been corrupted during the download. Delete it and try downloading it again.
The downloaded file may be a compressed archive or disk image that contains the file you want. If the file is from a trusted site, double-click the file to decompress it.
