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 replaced a customers laptop HDD today, was transferring back his data (100 gigs of photos and movies (.mov and ;jpg files)  I have 1803 on my PC where I had his data backup, I had installed 1709 on his laptop, which was downloading updates at the time of the transfer. My PC told me I was transferring 57 gigs of data, when I looked at the laptop after 3 minutes the progress bar told me I had 99 gigs remaining! 

    Imagine my surprise!

    I went back and checked, if I highlight all the individual files in a folder I get the correct size, If I ask for that folder's size I get a much smaller number. Folder and file types seem to have no impact on the issue. Notice that  the folder "Charlie***" shows 500 megs but when I open it and highlight the folders in it  it shows 57 gigs....Which is ALSO  wrong! There iare over 100 gigs in that folder

    LOL, Good luck :)

    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.

    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.

    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.
