Duplicate Files

[DaleMcNair]

Hey there,

Unsure if this issue is caused by issues with the onDrop prop callback. I was using the onDrop prop to check for duplicate files (I store an array in state to check for duplicates) until I realised that the onDrop call would prevent the component from continuing thus no uploads would occur.

I then tried to put the same duplicate check in the s3-uploader preprocess prop call, I'm able to have minor success via the next(file) method, however when I hit a duplicate I can't simply skip that file by not calling next(file), as it then cancels uploads for all further files in that drop.

Is there something I'm missing to achieve this?

Many thanks
