What I really want to do is check if the same file exists before or after uploading the file, is there a efficient way to do it?
Well, that’s it!
Edit: Actually it doesn’t matter if its after or before, as long as it can detect dups.

You can’t check before uploading the file.
Once it’s uploaded you could compare the file sizes then the MD5s of the files to check if they are the same.
