Copy a file to a NAS share

[ECommander]

Hi,

I'm using a Synology NAS with the Torrent Client enabled and a folder to watch for new files.

When I copy a .torrent file to the NAS share and the torrent was already consumed, I get an error that the torrent file already exists.
It is useful to me, for knowing if I download the same file twice.

But this works only, when I'm using "Altap Salamander 4.0" as tool, with Multi Commander I don't get the copy error.
Is it possible to implement the same functionality? Any idea how this works?
I understand that this is not a lot of information. I attach the message which I receive.

Thanks

MC currently do not support ADS  (Alternative data streams) it is on the list.. Problem is that lots of security software gets suspicious with software that deals with ADS. since lots of malware uses that to hide and then the risk gets higher that MC get more false positives flags from security software.
