Thank you, Tony.

I believe that you have provided the answer, from which, I can derive
the solution.

I was trying to move the file from the computer internal HDD, which
has most of the Linux partitions, including the home partition, where
the file is located, as ext4.

I was trying to move the file to a USB thumbrive - 256GB, which, from
this, I assume to be formatted to FAT32.

I could not use the cp command, as the USB drive name includes a
space, which is not recognised as a character within a directory name,
by command line commands (or so I believe).

So, the solution appears to be to get another drive - that I can
rename, to ensure that it does not include spaces in the drive name,
and, format it to either ext4 or NTFS, before writing to it.
