Curious about the "deleting" box & copying files

[Guest]

Hello

Nothing important here, I'm just curious

When I highlight files in Windows Explorer and the "deleting" box with the
progress bar hand around after the file icons dissappear, what is is doing?
Not sure because if I hit the cancel button at that point, it seems to have
no ill effects, including the deleted files staying gone.

When backing up fules to CDR, I've noticed that files copy to the pre-burn
D:\ folder a whole lot faster than if the same files are copies to another
folder on the same drive they origionate from, C:\ or E:\ for example. Why
is this and why can't the same thing be done when copying files to another
folder on the same drive?

Finally, I have sometimes wondered when the same file is stored in two or
more different places on the same comp, be it on the same drive or a
different drive, why it physically takes up two or more different (possibly
fragmented) spaces instead of only one (possibly fragmented) space and there
be two or more entries in the directory.

Thanx in advance

One other thing I forgot to ask. I'm thinking of how when a person posts to
a newsgroup, message board, forum, send an e-mail, etc., there's that number
buried in the data (not the android) sent from their comp that allows someone
who knows what they're doing to see if messages posted while signed in under
different names, e-mails sent from different accounts, etc., are coming from
the same comp. Exactly what determines & sets that number? Can it be
changed?
