Windows displays incorrect folder size information on UCB Files
Issue
On Windows 10 in Windows File Explorer, when you right-click on a folder and select Properties, Windows will incorrectly calculate the size the folder selected. The true size of the folder is in almost all cases much larger.
Cause
A software bug in Windows File Explorer was introduced in 2018 that causes this issue in Windows 10. At this time, we believe the UCB Files server does not play a role in this issue.
Resolution
OIT recommends using a free application such as WinDirStat or Space Sniffer. These applications provide more accurate size information with the added benefit of displaying a graphical representation of subfolder and file sizes in the tree. Note that they will not provide size data for folders that you do not have security permissions to access.
