Thanks :) you are totally right, the timestamp is not changed, so it
tries to rebuild (copy) :(
And it seems that it is the same for rsp files....
The only way I found to change the date is to modify the file (like that
the modification access date change), but I am looking for a better
solution. I found some tools (a touch for windows) to do that, but these
tools are not natively with windows :(

So have you got a solution to change the timestamp when copying, or
another idea ?

At least I thank you again for your help.
