I found a solution
When you use synctoy for the first time there must be an equal situation between the source map on D: and the target map on L:
However the program is not perfect, files are not checked completly.
When I have a new file in D: with a higher Kbps and I have removed in D: the lower Kbps file in another root, the new file is create in L: but the lower Kbps file in another root is not removed from L:
I think the program does not look at the roots info.
I want to thank you for your interest in my problem.
