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

Anonymous

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)

    This is a HUGE issue - it constitutes a major failure in how an OS MUST act if it's reliable, usable even. Where is MS on this? I'm not going to shorten paths / rename, that would mean moving potentially thousands of files to locations they do not belong in. If you have one folder to move / rename in, fine, but I'm a working pro who deals with many systems every day where backups need to be made & file / folder sizes need to be 100% accurate no matter where in the hierarchy properties are brought up. MS have been chipping away at the heart of what makes an OS an OS for several years now - this is totally unacceptable.

    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.

    Bump.

    OP must have had some files buried deep within the structure that got "revealed" when that folder name up above was shortened.

    Just ran into this problem with a backup 2 TB external hard drive that's showing only 59 GB used in File Explorer in Windows 10, but the drive Properties shows 843 GB used. As another poster mentioned, who's responsible if the folder shows 0 bytes size erroneously and it gets deleted? What exactly does M$ use internally to avoid this problem themselves?

    Ridiculous that M$ hasn't had any official presence since the very first boilerplate "send us a bug report" response, over 7 months ago.

    Just spent several hours undeleting a drive I thought I had lost tons of data from when I moved it from one drive to another - the folder size was reporting I was missing 50Gigs+ of data....

    Turns out it had actually copied correctly - all files were actually there - but were getting miscounted - it was the bug reported here I hadnt been aware could happen until now....

    MS please fix... its a real issue.

    Note: sometimes - the file properties on the file explorer RIGHT pane reports the correct file size - but properties on the parent folder gives incorrect file size when I do a file properties on the parent folder.
