>Has anyone found a way to have STRTOFILE() to respect the proper casing of the file name?

You can rename the file after your command with MoveFile API, since VFP doesn't respect the case.

See
Rename File

Here is what I use for the similar case of COPY TO command

	COPY TO (m.tcXLSFileName) TYPE XL5 && Oddly Using TYPE XL5 produces the file in the upper case
	MoveFile(m.tcXLSFileName, m.tcXLSFileName)
