OAS File Locations
Following is where you can find the locations of the Open Automation Software options, license, and other default files.
Config Files Folder
The Config Files Folder is a specific folder in the operating where the OAS options, license, custom objects files are located.
Linux operating system there is a ConfigFiles sub-directory located in the directory you have deployed the OAS Engine.
Note: If moving the OAS Engine folder in Linux make sure all files in the ConfigFiles sub-directory are moved with the OAS Engine.
Windows operating system this is C:\ProgramData\OpenAutomationSoftware\ConfigFiles\
Note: ProgramData is by default a hidden directory in Windows and you can use Windows Explorer to show hidden folders.
To view ProgramData follow these steps.
- open File Explorer options from Control Panel
- Then to View Tab.
- Uncheck “Hide protected Operating system files” and click on “Show hidden files and folders”
- Press Yes and then OK.
The OAS.Options file contains all settings defined under Configure-Options of the Configure OAS application.
The OAS.license file will be updated with an activation with the OAS Serial Number to enable product features and the number of tags in the license.
The OAS.GUID file will be generated the first time the OAS Engine starts on a new operating system. This contains a unique identifier for store and forward functionality after a system restart.
The OAS.CustomObjects file is generated any time a custom object is programmatically assigned using the OASConfig or OPCSystems component. This is also the file that will persist all user changes for the Web HMI Dashboard.
All options can be set using the Configure OAS application with Configure-Options or programmatically with the OASConfig .NET component, OPCSystems .NET component, or REST API for OAS. All options are persisted in the OAS.options file in the ConfigFiles sub-directory.

Use the Configure OAS application with Configure-Options-Default Files to specify the file path of the default configuration files to load when the operating system restarts. These settings are stored with the OAS.options file.
Use the Configure OAS application with Configure-Options-System Logging to specify the file path of the OAS System Errors, Communication Errors, and Transaction Logs. These settings are stored with the OAS.options file.

Windows operating system this is C:\ProgramData\OpenAutomationSoftware\pki\
