How to configure "Data" folder of PI Connector for UFL

Hi all!


First time I am using PI Connector for UFL and I am finding it a bit confusing to configure comparing to the interface.


The connector was installed on

C:\Program Files\PIPC\Connectors\UFL


For avoiding consuming too much space on C drive, I whish to configure buffer and data files on D drive.

So, the UFL.ConnectorHost.exe.Config looks like this:

    <add key="LocalDirectoryPath" value="D:\ProgramData\OSIsoft\UFL.ConnectorHost" />

    <add key="LocalBufferPath" value="D:\ProgramData\OSIsoft\UFL.ConnectorHost" />


The Output folder was configure via power shell script as we can see in the ConnectorGlobal.config.json file:

    "ConfigObject": {

      "PurgeTime": 0,

      "OutputPath": "D:\\ProgramData\\OSIsoft\\UFL.ConnectorHost\\UFL\\Output",

      "RestBasicAuthentication": 1,

      "RestClientVerifyCertificates": 1



My data source is a mapped drive on another server.


However, it looks like there is another folder, called Data, which I don´t know how to configure.

Apparently, the connector copy source files to this folder prior from reading them. Is this correct?

C:\ProgramData\OSIsoft\PI Connectors\UFL.ConnectorHost\Data


Besides the fact I don´t want it set on C drive, I am getting the following error:


Severity: Error

Timestamp: 05/23/2018 17:58:38.947

Message: [xxxxxx] Cannot delete file C:\ProgramData\OSIsoft\PI Connectors\UFL.ConnectorHost\Data\xxxxxxx\piData_1527025500190a.csv, the user running the connector does [sic] have the required permission


Although I have given the account full control to the folder.


So, how can I set the "Data" folder location?

And what kind of permissions do I need to configure for this folder,
