Please make sure that you have the view option " Allocated Space" activated when you are interested in the physically allocated space.Īnother possibility is that not all parts of the drive could be scanned due to access restrictions. The Windows Explorer and the TreeSize drive list do show the space that is physically allocated on the drive while TreeSize shows the space that is occupied by all files under a certain path.

There are some workarounds to gain access to those network drives anyway:

This is because Windows uses different user environments for non-elevated and elevated processes. One side effect of this is that you may not see your mapped network drives anymore (Windows 8 and later), or they all appear disconnected (typically in Windows Vista and 7) in all applications that run with administrator privileges. Since Windows Vista and later, Microsoft enforces more strict security rules on the operating system.
