Since installing the 1803 update, Windows File Explorer doesn't display the correct folder size if the folder is named 'Applications'.
There seems to be a bug that if the folder name is 6 characters or more and starts with 'Appli', the folder size shows significantly less than it actually is. For example if the folder is named 'Apps' or 'Appli', it will display the size correctly. If however it is named 'Applications' or 'Applix' or 'Appliy', then it won't display correctly.
The Feedback app doesn't work on my computer due to having telemetry settings set to 'Basic', therefore I am reporting the bug here instead.

2018-12-23T21:18:04+00:00 I'm using Windows 10 Home on a Desktop and Windows 10 Professional on a Notebook. On both systems, when I right click on a folder and choose Properties the size of the folder is incorrect. I know this because when I total the size of the subfolders beneath the folder it is much greater, in some cases more than two times, the size shown by the Properties of the parent folder. I never noticed this issue with Windows 7 or earlier versions of Windows.

2019-01-04T15:57:03+00:00 Use https://sourceforge.net/projects/tlpd/files/v4.6/ to determine long file names in this directory. 260 chars is the official limit- but when I run this I run it for 240.
The out put is a file list of long names-- try moving these out of this directory temporarily, or just shorten them- and that fixes the "size" problems.
I have 8.75 TB of files in a directory that has shown only a fraction of the file size in Explorer-- until I did this, now it shows correctly.
