I know that probably has been mentioned before but I just checked the size of the Bitcoin folder in appdata and it is now 17GB. Right now I have it stored on another drive and then mapped across, due to my OS drive being a small SSD.

Is there going to be any way for the dev's to be able to decrease this at all?

Imagine 10 years down the line and a 100 GB or higher Bitcoin appdata folder, that is always a lot of space even on a TB HD.
