Kendall Lister's questions

A Windows 2012 server is showing paths starting with D: and with D:2 in Resource Monitor, e.g.:

System        4      D:2\$LogFile
sqlservr.exe  1808   D:2\SQL\LOG\Sp2013_Config_log.ldf

Screen capture from the Disk pane of Resource Monitor showing file paths starting with "D:2\"

What does it mean when a path begins with "D:2\" rather than "D:\"? Is this particular to Resource Monitor?

I found this similar question, What does "C:0" mean in file path?, but I don't think we are using mounted volumes as in that question and it hasn't been answered anyway.

Assuming it is related to mounted volumes, I found this thread on TechNet that supports the suggestion that it is related to both mounted volumes and Resource Monitor but doesn't give any explanation:

Here is the view from Disk Management as requested:
