Is it possible to preview files that conflict while copying? For example, if you
are trying to overwrite an existing image by copying, perhaps show a thumbnail
of both images so that you know what they are? This can be applied to all sorts
of things - you could have stills of videos, or allow audio files to be played.

Additionally, you could show the information about the two conflicting files
e.g. file size, date created, date modified. If there are plenty of files, it
might be worth putting the different conflicts into a long list so that you can
simply use checkboxes or similar for each conflict.

Thanks
