That should not be relevant, though. That at most limits the ability for the
current working directory to be a UNC path, without first mapping it to a drive
letter. But it really should not affect the ability to invoke LilyPond and
pass in a UNC path for the input file. As an aside, PowerShell does not have
the same working directory limitation, and you can `cd` to a UNC path as you
wish.
But back to the issue, if LilyPond is ultimately calling CreateFile passing in
the file path as specified in the command-line arguments, it should be able to
open a UNC-based path providing there are no permissions issues. What I would
suspect is some quirkiness with MinGW/MSYS and Posix paths such that LilyPond
is not generating the correct API call.
As such, what would be interesting is to get a Process Monitor capture of the
failing case. That way, we can see which specific file I/O calls failed and
with which errors. Unfortunately, I no longer use the Windows version of
LilyPond, so I cannot immediately test this on my setup without having to set
up a VM first. If it is possible to run LilyPond in a portable mode without
installation, then that would save significant time getting a test environment.

I am trying to double-click a .ly file that is in a network share. When I
do so, the following log file is created:
\------------
\# -\*-compilation-\*-
warning: can't find file:
\`\\\server\fgasper\my\_docs\Scores\editions\conditor3-alt\_lyrics.ly'
error: failed files:
"\\\\\\\server\\\fgasper\\\my\_docs\\\Scores\\\editions\\\conditor3-alt\_lyrics.ly"
\------------
If I copy the file to my Windows desktop and double-click on it there,
everything works as normal.
