Now there are caching issues. For some incomprehensible reason Microsoft
decided to open the files being copied in cached mode. With large files, this screws up (already much screwed up)
Windows memory manager tremendously.


I thought this was fixed in Vista? No more copying a DVD and having everything
swapped to disk, so that when the copy finishes, programs do not respond for about
a minute on a machine with a fair bit of ram (2 gigs or so)..

Also, I understand there is finally a "Copy" API..
Before we had Read, Create, and Move wrapped to perform a copy as one
command. I read somewhere that with Vista, to improve network speed,
If you copy a file from Server A (on WAN) to Server B (on same WAN)
instead of copying every byte to you, then back to W, windows will
now just send your security credentials to A, and to B, then instruct
A to copy the file to B, without you in the middle. This saves a ton
of time reading and writing many bytes across the WAN link.
Home workers rejoice...
