NULL File - opening and understanding

Did your computer fail to open a NULL file? We explain what they are used for and recommend software that we know can open or otherwise handle your .NULL files.

What is a NULL file?

The .null file extension is used by some third party Windows programs for a corrupted data file format. When a program generates a file with corrupted data, the program may use the .null file extension for the file, in order to flag it as a file that can't be activated due to some issues with its content. These NULL files are normally placed in the same directory where the application that created these .null files stores generated files, or in a location that was selected by the user in the application during file generation.Since these NULL files do not contain any usable data, it's recommended to leave these files alone. There are no Windows tools or third party applications that can open and view the corrupted content of these .null files. There are also no programs that can fix these NULL files.There are also no third party applications or Windows utilities that can convert NULL files into the correct file format. The corruption of the data stored in these .null files may be caused by a lot of things, such as errors with the application that generated the NULL file, issues with the platform, or file generation timeouts.
