Correct format for network path for binary data storage in appsettings

Hello,

We are trying to setup redundant Survey Solutions (2 servers).

We would like to store binary data (signatures) in a samba store so that signatures are viewable from both servers.

There is [FileStorage] in both appsettings.ini & appsettings.production.ini, but we were unable to get the right format for samba path. (UNC) was used for AppData & TempData but were not successful.

The export does store export files to samba.
[ExportSettings]
DirectoryPath=\10.2.0.56\survey\export (double backslash on all)

Could you provide guidance on the right format to point binary storage to samba? and how the AppData & TempData are inter-related in the two files.

Thanks.
