NTFS Files

On an NTFS file system, what is the difference between moving a file between folders on the same partition, and between folders on different partitions, and why is it important to understand the difference?

If you move a file across partitions then what you are actually doing is copying the file and then deleting the original. because you have created a new file the file will lose any permissions it has and will get new permissions inherited from  the security settings of its parent folder.

if you move a file within a partition, then no new file is created - the pointer which indicates which folder the file is in is changed, but the file itself is not copied/recreated. Therefore any file permissions are retained and are not subject to the inheritance of permissions of the parent folder.

It all depends on how the data is moved.  If you are just talking copy and paste then the permissions will be lost going accross partitions and will inherite rights from the parent folder.  If you use robocopy you can copy while retaining the permissions across partitions.
