This was a much requested improvement from our users. Previously our maximum file count was 20 per upload transaction, but we have improved this to 50 files per upload.
This limit is in place to ensure optimal performance and reliability for all our users - because TransferChain's architecture works on client-side end-to-end encryption, cryptographic file splitting, blockchain authorization, and distributed cloud - but we would like to make sure our users have a seamless experience as well.
