Delete at first

If I try to synchronize from left to right, I sometimes get the message „Insufficient disk space“
The reason:
On the left side I have marked: “Delete all files not corresponding to the right side.
The program now starts copying and after a certain time the disk is full.
Solution:
The program should delete the files at start, not after copying.
Ok, one could do step 2 manually before starting copying.
But the other way round would be the better solution, I think.
