How to share files in virtualBox | Ubuntu Host and Ubuntu Guest
I was running a virtual machine Ubuntu12.04 in the host operating system Ubuntu12.04. In the virtual machine my development environment was already set and I want to set the same environment in the actual host operating system. The problem was that, I could not share some installation files from Guest operating system to the Host.

I was talking with my friends regarding some of the technologies we have been using in our jobs as a software developer. There I heard about Spring Boot.

First shut down the instance.Then from the command prompt hit the following command
The output of this is
0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%
The above command changes the virtual capacity of the .vdi file to 20GB.
Now comes the real problem. Only the virtual size is changed to 20GB. The real size of the partitions inside the image is still the same. You need to extend the partition manually. The added space is there but in the state of unallocated space which could be confirmed by the command
To extend the size of the partition (/dev/sda1), do the following steps.
