Re: Upload Problem(prevent a new copy of an existing file)
That is quite a detail of the default Share user interface, and it is not something that provides a simple configuration to switch. There is also some logic involved to determine if the name should be adapted or not. To prevent the renaming you'd have to make sure that the "showConfig.updateFilename" setting is never set to "true". Since the showConfig is usually provided from the code to trigger the upload, you might have to check/change in multiple sources (including 3rd-party addons that might provide a custom upload action/UI) to check that every instance is configured to your preference.
