Error copying file - 'Error splicing file. Input/output error.'

[Nick_C]

I am getting the following error when trying to copy a particular file:
'Error splicing file. Input/output error.'
I get this same error from File Manager and from a terminal prompt.

This is being copied to an NTFS partition so might be related to ntfs-3g. Also it is a bit of an obscure file in that the existing file shows as being 127Gb in size but it cannot actually be that big as the whole partition is only 37Gb! It was created by qemu-img converting a VM from hyper-v.

That can happen if it is a sparse file: a file with holes, data that has
not been filled. I did not know that ntfs could do that.

Before running qemu-img convert on the Win 7 VM I ran sdelete -z otherwise I would have ended up with a real 127Gb file, that is just how qemu-img seems to work. I didn't realize I would end up with a file that could not be copied. Is there any known way around this?

Thanks,
Nick

I'm sorry, I'm not familiar with qemu. I only commented on how a file can
be bigger than the available space.
