Hi Steven,

There's a file for each year of the program called NetDir.w? (? is the year). It will be located in the 15tax,16tax,17tax directory on each workstation. This file is normally in C:\Lacerte\1?Tax\

17tax will have a file called netdir.w7.
18Tax will have a file called netdir.w8. 

You can open this file with notepad and change the path to the desired one. (See attached image)  

Additional Information: 
OPT files in your Option folder contain all the user options for each person. (close to 12,000 options total per user!)
OPT001.w8 might belong to Bob
OPT002.w8 might belong to Carlos
OPT003.w8 might belong to Sarah

Example: 
Bob logs into his program.

First, the program reads the Netdir file to find the correct Option folder, Then it reads the Opindex to find the correct OPT file for Bob, Then it reads Bob's OPT001 file to load all the options for Bob. 

OPT00?.w? can be edited (Changes the Datapath)
OPMaster can be edited (Changes the Master options, which are the default set a new user gets)
Netdir can be edited (Changes the System file path)
Opindex is a list of people and contains Hex data so it should not be edited.
