1. Make sure you install the Guest Addition
Go to Device tab of your Virtual Box window, then click Install Guest Additions.
2. If you have problem in accessing the internet inside virtual box, then restart the guest OS.
3. To access the files of your Host OS, you don’t have to write the code again and again just make a executable fileName.sh file.
#!/bin/sh sudo mount -t vboxsf share /home/ananda/Desktop/from_windows
make sure you make it excitable. There are two ways to do that
From terminal
chmod +x fileName.sh
or you can do it from the GUI
write click on the file that you want to make executable, then click properties.
Then select the Permissions tab after that put a tick on the Execute filed.
