How can check file already exist or not ? #131

Hello I am using multer-s3 can you please tell me how can I check that file is already exists or not while upload file to s3. I want to skip file upload if file already exists.

Thanks

Unfortunately as far as I know S3 doesn't provide any exclusive writes, so this cannot be implemented reliably...
