On the other hand, for Windows Media Player, data can be accessed using the Files menu and then the relevant file will be opened for playback. A Mac user will need to drag the file from the player's main window to the Play dialog box, and then choose Play. The WMP allows the user to browse the file system for a file before it is played. The WMP players also differ in terms of the way they handle data and the way they allow the user to select a particular format. However, Apple Macintosh only allows a small selection of the formats that the WMP can read, such as AVI, FLV, MPEG, and MP4. Despite their different modes of operation, both the WMP and the MACM are capable of reading most common multimedia files and standard audio and video formats. A Windows Media Player can only play files that are already installed on the computer while a Macintosh Media Player can stream files that have been downloaded from the Internet. The WMP is designed for both Windows and Macintosh OS X operating systems. Windows Media Player is a multimedia player and library file application developed by Microsoft, which is primarily used for playing standard audio, video and image files on personal computers running Microsoft Windows, Pocket PC and Windows Mobile based devices.
