File locations

During the Workbench installation and platform commissioning processes, the software differentiates between two types of files based upon the content of the files: configuration and runtime data. Files and folders that contain configuration data reside in separate locations from files and folders that contain runtime data. This separation enhances security by denying general access to the runtime files and allowing each user access to only their personal configuration files.

As a result of separating configuration and runtime data, the system supports multiple home directories on the Supervisor or engineering workstation. These homes may be identified as:

The system home contains runtime files, such as core software modules, the JRE, and binary executables.
Workbench user home for each user contains configuration data, including option files, and registries.
A platform daemon user home for the Supervisor or engineering workstation contains platform configuration data.
Two station homes called, protected station home and station home, are part of each user home.

Homes on a Supervisor

The following table provides a summary of the Supervisor or engineering workstation homes with shortcut information.

Home in the Workbench Nav tree	Home in the Platform Administration view	Niagara 4 alias	Windows folder location and contents	File ORD shortcut
My Host > My File System > Sys Home	System Home	niagara_home	C:\niagara\niagara`-4.x.xx` Executables and software files	! (as in `Niagara4.x`)
My Host > My File System > User Home	N/A	niagara_user_home	`C:\Users\userName\Niagara4.x\<brand>` Workbench user home for each human user contains that user’s unique configuration files.	~ (unique to `Niagara 4`)
`shared` folder	N/A	station_home	`C:\Users\userName\Niagara4.x\ tridium\shared`	^ (as in `Niagara4.x`)
`stations` folder	N/A	protected_station_home	`C:\ProgramData\Niagara4.x\ tridium\stations\<stationName>`	^^ (unique to `Niagara 4`)
N/A	User Home	niagara_user_home	`C:\ProgramData\Niagara4.x\<brand>` Platform daemon user home (non-human user) holds platform daemon configuration files. Requires a local platform connection to view in the Platform Administration view.	~ (unique to `Niagara 4`)

Homes on a controller

On a controller there are two homes.

Home in the Platform Administration view	Home in the Platform Administration view	Niagara 4 alias	OFD location and contents	File ORD shortcut
Platform > Remote File System > Sys Home (Read Only)	System Home	niagara_home	`/opt/niagara` Contains operating system data.	! (as in `Niagara4.x`)
Platform > Remote File System > User Home (Read Only)	User Home	niagara_user_home	`/home/niagara`Contains configuration data and the installed and running station.	~ (unique to `Niagara 4`)
