What is a dir file and how do I open a dir file?
A file with the DIR extension contains a movie or animation project created with Macromedia Director. DIR files include project resources, links to externally referenced files, scripting code, and the timeline, which determines how the movie is played. Director movies can only be opened with Director. Some Director movies can be opened in Adobe Shockwave Player. Digital motion graphics, animated sequences and movie projects authored with the Macromedia Director software are also known as Adobe Director movie files, and these are digital video files stored in the DIR format. Adobe Systems purchased Macromedia in 2005, so version 11.5 and later of the Adobe Director software now use the DIR file format, and files affixed with the .dir extension can only be created and opened or edited using the Adobe Director 11.5 software or later versions of the software. It is possible for the content of these DIR files to include URLs of files stored in external storage devices which in-turn need to be referenced by the Adobe Director 11.5++ software if a user accesses associated functionality implemented into this program when viewing the corresponding DIR files. Scripting code project resources may also be packaged as the content of these DIR files by its creators. Timeline configurations and settings are also entered in the DIR movie files, since they define video playback. The Adobe Shockwave Player software can also be used to open and view the digital animated movie content of these DIR project files. The Adobe Director 11.5 software has a version for Mac platforms, while another version is intended for computers running on Microsoft Windows-based systems. Users of these operating systems can also use the Adobe Shockwave Player program to play a DIR movie. Most browsers developed for Microsoft Windows-based systems are integrated with support for opening and playing the video content of a DIR file through the functionality of the Adobe Shockwave Player program embedded into these Web browsers.
