Where I can find the tnsnames.ora file for my Oracle Windows client? I installed Oracle client for my Windows 7 machine. I can connect to a remote Oracle database using Toad for Oracle using the direct method (giving host, port and service name for the connection). 

Now I tried to find the tnsnames.ora file from the Oracle client oracle home, but could not find it. I could not find a NETWORK\ADMIN folder in ORACLE_HOME (C:\app\myaccount\product\11.2.0\client_1).

Where is this file located?
At least for older releases, I'd generally just create my own. It's a plain text file but you probably need to start with an example.
