Matching Windows path in props.conf

I'm trying to set up the Splunk for A10 Networks app. It expects syslog data on UDP port 514. My data is collected by NXLog, spit out into a file, and then consumed by Splunk. As such, I'm trying to edit a props.conf stanza in the app's directory from it's default, **[source::udp:514]** to match my file path. Example path: *D:\syslog\a10networks&adc_a10networks\[device name]\[file name].syslog*. How would I construct my source stanza? I've tried many variations along the lines of, **[source::D:\\...\\a10networks&adc_a10networks\\....syslog]** (I have tried escaping the ampersand in my path). I'm running Splunk on Windows if it matters.
