Unfortunately there is no Help file with this utility. Some of the improvements added to the last versions are displaying the time of the errors, an auto-clear option to clear the listbox after finishing, a fixed I/O error 130 when stripping the index, fixed bugs in the “Cut out bad parts” option, turning on the “Keep original file” option by default for safety purposes and displaying the name and the number of errors after completing a file. One of the repairing methods used by DivFix is rebuilding the index, which can work in the case of partially downloaded files with blank spaces.Īnother solution is stripping the index, which is a good idea when you have an intact file but which doesn’t let you move around it.ĭivFix is already outdated and its last version was released in 2006. You can even run it from an external memory device. Why should the entire file be spoiled because of some missing frames?ĭivFix can solve this problem by rebuilding or stripping the index part of the movie, which is found at the end of the file.ĭivFix is a portable application and you don’t need to install it to your computer and modify the Windows registry at all. Frustrated because of partially downloaded movies which cannot be played?
