To small disk C:/

My disk C:/ is to small so when I install new wallet of some coin i make shortcut wit -datadir=D:/< folder name of coin> and start wallet from this shortcut.
Can I change datadir for nem folder to be not C:/Users/<name of user>/nem and to be D:/nem
If it is not possible dev can put in settings possibility to change way to this directory.

Same issue. C is an SSD drive, need to move nem folder to spinning disk. How does that work?

The configuration file config.properties offeres a solution for that. Just edit the entry

nem.folder = %h/nem

to point to a folder of your choice.
