VMware Tools is an implementation of the virtual machine host and share files with drag and drop tools to support freedom of function, if no VM tools, so there is no copy and paste the virtual machine switching is inconvenient.
Not a long time to open a virtual machine, an attempt to drag the file to the Windows desktop virtual machine, too strange fails, then reinstall VMware Tools does not work, try a lot of ways finally resolved.
[Summary] its you again reinstall VMware Tools or shared folder, it is better to use the following quick solution!
Sequentially execute the following command line in Ubuntu terminal:
sudo apt-get autoremove open-vm-tools
sudo apt-get install open-vm-tools
sudo apt-get install open-vm-tools-desktop
