Opening DDAT files
Did your computer fail to open a DDAT file? We explain what DDAT files are and recommend software that we know can open or convert your DDAT files.
What is a DDAT file?
The files that contain the .ddat file extension are temporary video files that have been created by the DivX Player. These files are created by the player as a video file is downloading from the Internet.
The .ddat files contain a partial AVI video file. The .ddat extension will be given to the file until the video download is complete. If the video download is interrupted, the download can resume at the point in which it left off according to the DDAT data. Once the download has been completed, the video file will be renamed with the proper .avi extension.
Software that will open, convert or fix DDAT files
Try a universal file viewer
In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
