I use Windows at work and something I really like about it is that Windows will automatically rename a file if another one exists with the same name. For example if there is a file on your desktop called somefile.doc and you download or copy another file with the same name to your desktop it will automatically rename the new file to somefile(1).doc, allowing the 2 files to co-exist without you having to manually change either name. Is there a way to make OSX do this automatically?
