I am trying to copy a 4.26 Gb file to a USB HDD.
The copy proceeds okk then it stops with a message to the effect that there
is not enough space on the destination disk.
Wiztree shows that the destination disk has 1.2 Tb free.
Can anyone throw any light on this ?
TIA

Just copied a folder size 27.4 Gb with no problems.
Must be something wrong with the file.

Just a guess: FAT (16/32) format?

More information about the USB HDD filesystem could help, but I guess
you just have the wrong filesystem for files >4GB.

FAT disk? :-)

What is the file system on the external hard drive? (In Explorer,
right-click the disk and select Properties. The file system is shown
on the first tab of the Properties dialog.)

For files larger than 4 GB, you need NTFS. The message "disk full"
isn't very helpful, if I'm correct in suspecting you've got FAT32.

Not necessarily.

A folder's size on disk is always negligible, because all it is is a
set of pointers to the files. As long as each individual file is
under 4GB, the aggregate size of the files in the folder doesn't
matter. (Well, "doesn't matter" as long as you haven't filled up the
disk.)

Thanks for all the help.
I reformatted the HDD as NTFS and the file copied with no problem.

Depending on intended usage, exFAT can be a better alternative for
external media.

That's a good point. The USB port in my car will handle exFAT but not
NTFS. A quick Google search shows Macs can handle exFAT but not NTFS.

Apple claimed at one time, that NTFS support was read-only.

And this stemmed from NTFS drivers being "reverse engineered"
and not written from a publicly available spec. "Not being supported"
on a Mac, is not entirely correct -- it's conditional support.
Perhaps no different than the conditional support on Linux
(not every NTFS feature is supported on Linux either, yet
this does not prevent people from using what support is available).

The real reason at the time, might have had to do with
licensing terms or patents.

Now avoidance of NTFS comes from reparse points, and only
Microsoft has a driver which understands the reparse points.
This makes the "spec" for the file system, effectively hidden
again. Linux, for example, cannot arbitrarily delete files
any more. If they have New Style compression applied to NTFS
files, you get "I/O Error" from Linux.

Paragon has an NTFS driver, which they were selling. Then, a few
years ago, they donated their driver to the Linux kernel. As is
normal for kernel submission, the code needs to be "cleaned up",
because stuff running at kernel level has all sorts of
restrictions on what is possible. When the Ukraine thing
started, the Paragon developer went underground and could no
longer be reached via email. And the donated driver ? It
sits in limbo, and the existing NTFS drivers continue to be
used.

So when there is a discussion of "NTFS support", it's not
exactly a "binary property" and is un-deserving of a simple
tick box indicating "yes or no". There are many levels of
potential support. Nothing third party is "perfect". I
tested the Paragon driver, and my summary would be
"not ripe yet" :-)

When Apple lists their support a particular way, they are
not "over-promising and under-delivering". A user can still
plug an NTFS USB stick into a Mac and try it out and "see
what happens".

*******

NTFS trivia:

1) You can't mount a hibernated C: drive. It must be shut
down properly, for a third-party OS to access the partition.

2) Modern Windows damages MFTMIRR and $BITMAP (the Windows 7 CHKDSK
can fix this for you).

On Linux, they do an MFTMIRR check and they will tell you whether
the partition can be mounted or not.

sudo ntfsfix /dev/sda3 # Repair select metadata on third partition

sudo mount ... # Now, your favorite mounting method will work
# Most people don't use command line, and this
# is a single click in a File Manager window and
# away it goes. That's referred to generically
# as "automounting", since the mount point is made
3 for you, and disposed of later.

While the Linux OS automatically unmounts foreign partitions at
shutdown, I like to unmount the NTFS ones, before I select
shutdown from a Linux menu. On Linux, there can be some
coupling between "unmounting" and "ejecting the whole stick".

I have a TV set that reads NTFS but not exFAT, and saw one that handles
neither. exFAT is still relatively new (was introduced only in 2006).
However, if exFAT is handled by the devices involved, I do prefer exFAT,
for reasons explained by Paul.
