Windows File Explorer Not Showing Correct Folder Size If Folder Named 'Applications'

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.

Windows 10 Pro X64 (17134.1, 1803)

    I have almost the same problem, but it seems to have nothing to do with the file name. Since I upgraded my windows to 1803, my explorer behave weirdly in reading folder size.What it shows is different from the the real size of all files it contained.The difference could be so huge, for example, the folder size is read to be only 649 MB, but the actual files and folder it contained is 9,92 GB.

    I also see this issue-- with all folders.

    I have v1803 on my "server" computer. this computer has a 15TB spanned drive created on it.  My Onedrive folder is about 350GB in size.  Windows only tells me 13.9GB in folder properties.   I have had to use 3rd party folder programs to show it's true size-- 350GB.  

    I have another Win10 1803 device that accesses this share.  It shows the SAME SIZE of the folder- 13.9 GB- via a network share?!

    Now, I have a 3rd computer-- v1709.  It is showing the actual folder size correctly- via network share- as 350GB.  

    The last computer is updating now to 1803.  I suspect the same folder size issue will show itself to be true.

    Checking any other known folder continues to show incorrect folder sizes in Properties.

    The same issue started for me since installing the 1803 update. I first noticed it when I checked the size of a folder I copied from one drive to another, to make sure it copied correctly. Windows Explorer is reporting the size as around 3% the correct size. WinDirStat reports the correct size for the same folder. Windows reports the incorrect size on both the source and destination drives.

    Even I am having the same issue. I have installed April upgrade. A folder which is 45 GB is displayed as just 19.5 GB.
