Wrong calculation of folder size by Windows

Anonymous

Hello,

I noticed today that my Windows system does not properly calculate folder sizes.

I'm actually trying to make a backup of all my personal and work content. When I check the whole backup folder size under properties, It shows me around 10 Gb. But when I open this big folder and select a subfolder, It show me 30 Gb... This is kind of really annoying and I think it's a major issue Microsoft should fix ASAP.

I would like to say (because I didn't find anywhere else to post it) that in my opinion, Microsoft lacks ways of collecting feedback from his clients. There is nowhere we can manually report bugs and crashes.

In any ways, I think that showing correct folder sizes is a really basic task that an Operating System should be able to do. Such a bug is inacceptable for a leader like Microsoft, and I honestly consider going along with Apple if this issue does not get quickly fixed. My computer will soon need to be changed in anyways.

Meanwhile, if some of you guys have found ways to go around this major issue, feel free to share them :). Thank you!

Here is my technical information :

Intel Core i7-3720QM 2.60 GHz

64 bits

Windows 10 family version 1803

Installed on 2018-06-20

O.S. version 17134.112

Many thanks is advance,

Antoine

Hi Antoine_795,

It is widely reported that version 1803 of Windows 10 has introduced a bug into Explorer.exe

It is because it cannot read the metadata of files correctly, it mixes up the size and dimensions for example

Therefore it cannot calculate the size of a folder, especially if it has sub-folders, it also cannot calculate the spare space on a hard drive . . .

In the meantime, while we are waiting for Microsoft to fix this bug:

Click the link below to download a small free utility called Treesize - it is a great utility . . .

Using that tool, you will instantly see the size of all folders (always missing form File Explorer) and where space is being used on your hard drive . . .

    For this thread about file properties not tallying to what's expected I represent many thousands of users of Windows 10, likely to come across such problems and panic.

    When it comes to Windows Updates and CompatTelRunner.exe carrying out a DoS on low end systems that were all incessantly nagged to be upgraded to Windows 10, I represent EVERY SINGLE USER of these low end systems who experience dire performance and immense productivity frustration.  They spend money with local IT businesses and the problem just comes back next time WU gets more updates and spends literally 6 hours installing it all.

    People hate technology because of nonsense like this and I've taken time to figure out what's wrong.  People ditch Windows because of quality issues like this and move to Mac.  So if he was doing his job properly, Satya should absolutely listen to what I'm saying.  He should be phoning me to understand what's wrong in many aspects of Windows 10 for so many people and take urgent action to sort this mess out, I have quite a list.  Sorting out these many quality problems is far more important than adding a load of new features that 0.01% of users actually use.

    I also represent every person who's concerned about climate change because of the intense processing required to perform Windows Updates multiplied by 800 million devices running it, what an absolute disaster!  Computers should not be spending hours on end of so much processing just to figure out what updates are required and install them.  This absolutely should not be a processing intensive task, it boils down to comparing versions of a few thousand OS files, working out dependencies and shifting some files around.  WU never used to require so much processing so the task can definitely be achieved with far less energy use.

    TLPD does not need to be installed and can just be run. All it does is list file paths that are longer than the limit you specify.

    After editing file/folder names to reduce the offending file path lengths on my PC, File Explorer now reports the correct sizes for all folders. This appears to have worked for other people as well.

    I submitted valid (and nicely worded) feedback in the Feedback Hub last year:

    No response, completely ignored. 

    I want to make this OS better, how do I get through?  What is Satya's phone number?

    Great, submit another feedback, for this problem, or vote and comment on existing feedbacks on this issue.

    Yes, there rarely is any response. Most frequently (and that is vanishingly rare!) you just get an email that the feedback is "under review".  Even less likely you will get a private mail back with additional questions.

    These feedbacks are our best way of getting direct contact with MS staff. (Remember, "feedback" has only been around for over a year, before that we had NOTHING!)

    Your other option is to work for a company that spends hundreds of thousands (millions?) of dollars a year on MS products. Then you will have a dedicated MS customer service rep who you can complain to with some hope of the problems being fed higher up the food chain.

    Trying to talk to Satya is a waste of time. If you ever managed to get through to him, he would (politely? or not?) tell you he has better things to do with his time than worry about individual consumers and specific Windows issues. He has to worry about the corporate "big issues", the "vision" etc ad nauseum. And of course he has to worry about how to spend and invest his $24-25+ million last year in "good performance" bonuses .  Priorities man!

    @Nickdir

    No, although I was one of those who identified the length of file name (inclusive of file path) as one very likely source of the problem, reducing file lengths on your own or using third-party programs for a "fix" is not really a true solution. Plus it is unclear if using third-party programs might cause conflicts - if not now, then perhaps later when Microsoft introduces its own solutions or "updates". A real solution can only be found by Microsoft itself, and for that it appears we have to wait for ever.

    @Rohn007

    The posts and responses by users "megawhite" and others were actually both reasonable and appropriate. They helped to highlight common problems encountered by users, as well as their magnitudes and frequencies of occurrence. Several months ago, when I found folders supposed to contain gigabytes of data suddenly turned into megabytes, at first I was sure my SSD or hard disk was about to fail. Having seen numerous users reporting the same thing, it now became clear that it was a Windows 10 problem.

    It is recognized that this Forum is not an "official" channel. But isn't Microsoft interested in knowing the most common problems encountered by users? Wouldn't at least a few of the "MS Developers" occasionally come here, if not to read the messages, at least to look at the titles to get some idea about the nature of the complaints? Or even if they don't visit this forum, don't they themselves use Windows 10 and yet are totally unaware of these problems? In the event that they totally don't care, then even if we contact the "MS Developers" through that site, it would be like - as you said - talking to a wall.
