I’m downloading Iconica Ensembles Trial Version now on Steinberg download Assistant. On the Steinberg Download Assistant, it is reported that the total size of the Iconica Ensembles is 50.24 GB. Steinberg Download Assistant is downloading this file to my computer in Download>Steinberg>Iconica Ensembles. No problem so far. 
But downloading is a long process. While the download process is still running, although the 38 GB of this file appears to have been downloaded in my computer, the Steinberg Download Assistant seems to have downloaded 18 GB of this file. Why is this problem caused?
