DCR is the file extension used by animated movies created by Adobe Director, formerly known as Macromedia Director. The extension is one type of flash file that can be played in the Adobe Shockwave player. Files written in the DCR extension can be opened and played in the shockwave player, with or without an Internet connection, as long as both the DCR file and the media player are both installed on the computer's local hard drive. It's very easy to install and use DCR files, even with basic computer knowledge.
