Re: Full Diskette On File Replace
I dont know the answer but I would suspect its by design, ie the copy
process first reads the size/free space of the destination & terminates if
insufficient free space, without recognising that you will be replacing an
existing file of the same name. - From recollection of pre Vista the floppy
copy physically starts, then bugs out if insufficient free space, so the new
copy is an improvement, but they forgot to impliment the replacing origonal
:(
A bit of a bugger in your case, but I would further suspect that if there
was a registry workaround that this would also impact on all such copy
processes, which might then have further unintended consequences.
Now I know you said 'dont ask' but I'm intrigued :)

Re: Full Diskette On File Replace
Hi, Joel.
Vista uses NTFS natively and reverts to FAT only when coerced. NTFS is a
"journaling" file system which means, among other things, that it first
writes the new copy and verifies it before deleting the old copy. This
means that it practically never fails in the copy operation, even if there
is a power failure in the middle of the job. In virtually every situation,
even if the new copy was unsuccessful, the old copy is still there, intact.
If FAT encountered such a problem, you might be left with both the old and
new files corrupted.
Like you, I'm an advanced user, since the first TRS-80 in December 1977.
And I kept FAT for a long time so that I could use Norton's utilities (when
Peter still wrote them) to do bit-level editing in the FAT or directory (and
that was OFTEN necessary!) I've never learned to read NTFS's MFT - and I've
sometimes wished I could. But today's tools - especially Symantec's - are
so pretty that they are useless for such jobs; at least, they were as late
as about 2000 when I gave up on everything but their NIS, and 2005 when I
abandoned even that. One of my primary partitions is still formatted FAT32,
but its days are probably numbered. My computer still has a "combo" floppy
drive, with both 3.5" and 5.25" in a single unit, and I still have a stack
of 5.25" disks over in the corner - but it's not likely I could read any of
those now without some ancient Norton utility to translate from TRSDOS - or
whatever I formatted them with.
My recommendation is that you buy a USB flash drive (you can get an 8 GB
(and I mean "G") drive for under $50 these days and 1 GB models are almost
free), format it NTFS and use that for all your backups. The aggravation
factor relief alone makes it worthwhile. ;<)
