DIT, Active Directory Information Tree File (.dit)
The DIT System file format
DIT files and the program that uses these files are part of the Windows Server products. They are used by a network and computer directory service of the name of Active Directory Data Store. The information inside the DIT file is also known as a directory information tree. This means that the file stores directory information in a hierarchical way. Without the DIT file, Active Directory isn’t usable, hence why it is often referred to as the heart of the program.
Technical details of DIT files
The information saved in the DIT file contains information about network objects and their hierarchy. Furthermore, the DIT file contains the access permissions of these objects. By default, DIT files are all saved with the same name, namely “ntds.dit”. Renaming them is, of course, possible.
