Basically, .ND files (Network data files) are configuration files that permit the QuickBooks software to access the company file in a multi-user environment. These files are created by the QuickBooks Database server manager (QBServerUtilityMgr.exe). These files identify the database server used by the program.
In simple words, when QuickBooks tries to access the company file over a network, the .ND file acts as the bridge.

- Another fact of .ND file is that it is 1 KB in size and is a text file. This file can be easily opened and edited in Notepad and can be identified with a text icon.
