I have tracked the issue down to openFile in kernel32. It does not support file names ending in dot. It seems like filenames ending in dot are forbidden on Windows, but it is still possible to create them, e.g. with "notepad sherry.", and they can be opened with openFile on Windows.
I'm starting to think that this might not be a problem with OpenFile because you see them as normal files on Windows without the trailing dot. I can see files with trailing dots on Windows 7 with an NTFS partition if I create them myself. Which version of Windows are you using?
Btw I can't create files with trailing dots with notepad anymore. Echo works fine though:
echo Wine > "\?%USERPROFILE%\sherry."
You can delete it again using the following command:
del "\?%USERPROFILE%\sherry."
