### 3.1.1. The Site-wide Configuration Files

If you are accessing your ANSYS CFX files from a remote file system, your System Administrator may create site-wide resource configuration files. ANSYS CFX first looks for such files in the following order:

1. <CFXROOT>/config/cfx5rc-<host>.txt

2. <CFXROOT>/config/cfx5rc-<arch>.txt

3. <CFXROOT>/config/cfx5rc-<os>.txt

4. <CFXROOT>/config/cfx5rc.txt

5. <CFXROOT>/config/cfx5rc-site.txt

where:

- host is the hostname of the machine on which ANSYS CFX is running.

- arch is the architecture of the machine on which ANSYS CFX is running.

- os is the operating system of the machine on which ANSYS CFX is running.

You can find the value of host, arch, and os by selecting Show > Show System from the menu bar of the ANSYS CFX Launcher. On Windows, the value of os is `winnt`.

Note: Any resources set in these files will affect all users of ANSYS CFX, unless users override these variables in their personal user’s ANSYS CFX resource configuration files.
