Hi,

fopen can also work with UNC path, which does not have the MAX_PATH=255 
limitation:
- https://msdn.microsoft.com/en-us/library/yeby3zcb.aspx
- 
https://msdn.microsoft.com/en-us/library/windows/desktop/aa365247%28v=vs.85%29.aspx

A possible workaround would be to prefix the path name with "\\?\" then.

If there is an intermediate cmd.exe, I suspect passing filename with the 
previous prefix works as well.

How to debug at which point things start failing?

Best,
