Document upload twice with suffix

[luca]

Hi all,
when I update a document in Share two times, the second gets a progressive number as a suffix.

It's possible to customize this behaviour?

In Alfresco Explorer I get an error message and this is better because at least i'm warned of the duplication of the document.

Hi,
this behaviour happens to me when I a perform a copy/paste operation in a target folder already containing a file with the same name.
In my experience Alfresco correctly responds with an error against a node name already existing upload attempt.

Regards,
Andrea
