mount: unknown filesystem type 'vmhgfs'

It was a trouble sharing a host folder in the guest linux operating system after upgrading the VMware workstation to 12.0 from version 10 on windows 10

 root@rac1 mnt]# mount -t vmhgfs .host:/ /home/oracle  
 mount: unknown filesystem type 'vmhgfs' 

Solution: (run the guest operating system inside the VM)

 [root@rac1 mnt]# /usr/bin/vmhgfs-fuse /mnt  
 [root@rac1 mnt]# df -h  
 Filesystem      Size Used Avail Use% Mounted on  
 devtmpfs       4.9G   0 4.9G  0% /dev

 tmpfs        4.9G 9.1M 4.9G  1% /run

 vmhgfs-fuse     460G 400G  61G 87% /mnt 

Above you see that /mnt is mounted now, it was required since our shared folders get mounted inside this.

Now my shared folders are visible in the VMware operating system.

 [root@rac1 ~]# cd /mnt/  
 [root@rac1 mnt]# ls -ltr  
 total 12  
 drwxrwxrwx. 1 root root 4096 Jul 25 00:18 18c installation  
 drwxrwxrwx. 1 root root 8192 Jul 25 10:08 Database Products  
 [root@rac1 mnt]#  

Hope it would help !!
