I downloaded some ZIP files on my iMac. My Realplayer doesn't accept these files. How can I change a ZIP file into a video file with extension AVI, MP4 or FLV in order Realplayer can accept the file?
A ZIP file is used whenever you archive files and this file format belongs to WinZip. When you use that software and archive files, the output will be a single file with ZIP extension. Most of the archiving applications have the ability to extract the contents of a ZIP archive. In your case you need to use Stuffit Expander to extract the contents of the archive. While extracting, you will see the contents of the archive you have. Then use Realplayer to open the extracted files (in case there are video files).
