Well, I think the real issue is that Windows controls will not load a file with a path > 255 characters. The workaround would be to use the short form version of the filename. See the Windows function, GetShortPathName.
thank you for the hint. The ExtendedPrefix (\\?\) removes the MAX_PATH restriction. The following code works fine to me:
ImageEnView.PdfViewer.LoadFromFile(VerifyPath(Path));
function TfMain.VerifyPath(Path: String): String;
begin
if NOT Path.StartsWith('\\') AND (Length(Path) > 255) then
Result := '\\?\' + Path;
end;
