: We considered this, but it is problematic because it is perfectly valid to have a file with external file attributes where none of the Posix attributes is actually set (i.e. an empty set of Posix files attributes). This wouldn't be distinguishable from the case where a file has no external file attributes. So it seems we have to resort to throwing an IOE?
Maybe although it would be a bit awkward to deal with. The issues around this remind me a bit about mounting fat32 file systems on Linux or Unix systems where the fields in the stat structure are populated with default values. PosixFileAttributeView::readAttributes is essentially the equivalent of a stat call. This might be something to look at for the file owner at least. -Alan
