deleting files when copying
Is there a way to set Windows XP so that when it overwrites folders when copying, it deletes old content that should not be there in the folder anymore?
Say I have a folder F1 that contains files a, b, and c.
Then I copy that folder somewhere else. The copy is F2 and it contains copies of a, b, and c.
Suppose I delete c from F1.
Then I copy F1 again, overwriting F2.
I find that c is not deleted from F2, even though it does contain the updated versions of a and b.
I think windows is trying not to delete files if it's not told to do so explicitely (i.e. it's only told to copy, not delete).
There must be a way to set Windows so that it does delete files from folders if the folder in question is being overwritten and the overwriting folder doesn't contain those files. Is there?
