In order to use share folder you have to install guest additions in VirtualBox. In this page I will show you how to install it. Click devices -> Install Guest Additions... and wait a minute. Open terminal in CentOS7. Before installing it you need make sure your environment is OK.
yum install update
yum install kernel-headers
yum install kernel-devel
yum install gcc*
yum install make
After installing above packages you can mount iso file and execute install command.
mkdir /mnt/cdrom
mount /dev/cdrom /mnt/cdrom
cd /mnt/cdrom
./VBoxLinuxAdditions.run
This will take few minutes. After installation you can config share folder between host and virtualBox.

Click devices -> Shared Folders.. and config share folder path and share folder name.
