Share files between Linux host and Windows guest

I am trying to share files between Linux host and Windows guest and I came across the link:

Use virt-manager to share files between Linux host and Windows guest?

As suggested in the third answer, I followed the steps:

1. 
   

   Find the offset of your file system (since it is a disk) using fdisk:

   
   

   
   $ fdisk -lu Win.img
   
   



2. 
   

   Mount the image using command:

   
   

   
   mount Win.img /mntpoint -o ro,loop,offset=32256
   
   

Here,this seems to be promising approach. I am able to see the files of Windows guest VM on Linux host. However, I am not able to see any changes on host side if I make changes on guest unless I remount the image again.

Is there anyway to refresh that memory so I can see changes on host side too?
