a volume is a term for disk space.

Disk is physical volume of disk space.
Partition is logical volume of disk space.

But volume also means dynamic disk space in the case of dynamic disks in Windows Server 2003. That is, logical disk space that may or may not be in the same physical disk.

For the permissions thing, you might want to think of what is happening to the file itself (I'm very tired and it's been awhile since I thought of this, so someone stop me if I'm completely off :P).

When you move a file within the same volume/partition, the data doesn't actually move, it's just logically moved in windows, but the physical data stays in the same place, so it retains its permissions.

When you copy a file to another (or the same) volume/partition/disk, a new copy of the data is made which inherits its parent's permissions.

When you move a file to another volume/partition/disk, a new copy of the data is made on the blah, which inherits its parent's permissions, and the original file is deleted.

So essentially if you don't make a copy of the data, you'll keep the permissions intact. If you make a copy, it will inherit the permissions of whatever parent folder it is given.

Of course there are exceptions, but this is the default.

when you move the say folder/files to new partition/volume/disk
the permission are then taken from the new part/vol/disk

correct..that is my understanding but if moved or copies within
same part/vol/disk...then the ntfs perm remain?
correct

When in doubt, try it out. That's the best way to learn, and you won't learn bad information that was wrong in a book.

From what I have read, a move within a partition/volume is simply a pointer change, so the permissions don't change.

But a move from one partition/volume to another is a copy/delete so the copy rules apply, which is an inheritance from the new parent folder.

Sie

Same Volume
Moved files retain NTFS permissions
Remembered by - When you move house within a city you retain all your own things
Copy files inherit NTFS permissions
Remembered by - When you copy yourself (IE: have a child) they inherit things from you

Different Volume
Move or copy inherit NTFS permissions
Remebered by - When you move to a new town or city you have to start anew and take on things from that cuty

Its the silly things that make it stick in my head, i try to link it to something as it makes it harder to forget

As far as my head remembers right now but it has been a very long day!!
