This feature can be disable, to increase disk speed:
  • Click on Start, type cmd in the Search Bar> right click "Run as admininstrator".
  • Once the commnand prompt is opened type the command below:
  • fsutil behavior set disable8dot3 1
    • Where 1 = disable
  • Restart your PC

To enable this feature back, use the following command:
  • fsutil behavior set disable8dot3 10
    • Where 0 = enable
