How to add Disk storage to Hortonworks Sandbox 2.5 VirtualBox?

[#1]

Can anyone help me regarding this? The default hard disk storage was 48GB which is 90% full for me therefore less space for HDFS. can anyone guide me with the steps on how to increase the storage space of Hortonworks sandbox for Virtual box?

The sandbox shares the uderlying harddisk on which your VM runs. To increase the default storage footprint, go to VM where you have mounted HDP sandbox, go to settings, choose storage, and add a new storage.
