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.

OS Version:

Windows 10 Pro X64 (17134.1, 1803)

    Same here. Multiple drives and TB's of information all displaying inaccurate sizes. Sometimes you just select 5 files in a directory that add up to 42MB, but the right click properties claims 0.99GB. It's all over the place. Making backing stuff up and finding files that need to be removed extremely difficult to the point that I have given up. Too much information to sort through without the proper help from Windows.

    Yes, I understand... this thread has been open for quite some time without any "fix" other than shortening the file names to under the 260 char limit.    I hope they will do something as well to repair this.

    The good news is that the files are not lost- and using a 3rd party directory program will show the actual folder sizes.

    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.

    Suffering the same problem on a brand new Dell laptop. The problem was reported in May and now is December. Eight months without a fix of these very serious problem? I'm very disappointed with Microsoft!

    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.
