How to set adobe creative crowd so that it automatically skips the same items

I copied the photo files from my photographer's SD card but had to stop copying in the middle.

Therefore, I tried to upload them to the Creative Crowd so that my photographer could add all the files from the SD card again. I supposed it automatically skipped the same files, which created copies and cluttered my folder instead.

How can I set creative crowd so that it skips the same files?
