Navigating in Windows Explorer

When working with projects, keep in mind that the contents of a project folder are not locked. However, it is not recommended to drag in or out any files that were placed there by NetPoint.

Project folders CAN be moved in and out of parent directories. However, we recommend keeping them all in a single location, so that browsing in NetPoint is less cumbersome.


  1. Open Windows Explorer.
  2. Browse to the location where the project was saved.
  3. Double-click the folder which contains the project name.
