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

Dave,

Wow!

Thanks for that show stopping thought.

Now you have me wondering if I might have already done that to either myself or worse, a customers overcrowded back up drive that was absolutely jam packed with backups of backups (He thanks his Iphone for that little disaster), for some reason Time Machine also backed up the previous backup's data, and yes, eventually it filled a 1.5 TB hard drive and he came to me because his last boot took a half hour :)

I do however recall deleting a few folders that showed 0 (empty folder)....I sincerely hope they were

Ugh!

Other posts confirm that this is a path length problem.

Why this matters:

* The potential for loss of data seems very real. One scenario: a folder containing a set of nested folders forming a long path that breaks folder properties, with no files in any of the folders. This top-level subfolder is followed by other subfolders with thousands of files. Folder properties would show 0 files thanks to this bug. User shift-deletes the root folder thinking it's safe and watches in horror as their data is purged.

* Browsers and modern dev tools like npm create these paths all the time. This is not rare or unusual.

I am seeing a similar issue. A parent folder shows 11.9GB in size, but the sum of the sub folders is 150GB. This was for an Amazon Drive file sync folder... I re downloaded my amazon drive to a new folder and used beyond compare 4 to calculate more detailed comparisons between new and old. This appears to be a windows issue.

I have exactly the same problem. I have seen this before some versions of Windows ago. Looks like they reintroduced this problem. The funny thing is when I move the directory to another directory and then ask for the size I get another size (still not the proper one).  When I move it to a directory that i just created I get the wrong size. There seems to be a problem with newly created directories since build 1803. 

Did some test: It has definitely something to do with the name of the directory above the one  you are asking the file size off. When I rename that directory to something completely different I remove the problem. When I rename it back I have the problem again.

Did some more testing. The problem is worse when the name of the directory above is longer then 8 bytes. below 8 bytes I get more data reported then above 8 bytes but still not the proper amount. This is very weird.

Hi,

Same problem.
