At the moment not in all cases all the metadata. Recent kernels have an
extended statx() syscall that AFAIK is not yet fully supported in user
space tools. It will support things like a creation time or the maximum
filename length or file size of a filesystem while unlike stat() also being
extendable. Once fully supported desktop environments or cp/rsync and so
on could bail out on copying a file larger than 4 GiB to a FAT32
partition instead of copying 4 GiB and then stopping due to an error.
