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 . . .

    I hope MS is monitoring these dialogs; they really need to fix the file size issue, they should be embarrassed! 

    #2

    Quit adding "features" and fix the things that are really useful.

    #2

    I fully agree, but that is not the way that MS makes money.  Market more features, faster, does (at least that is what the Marketing monkeys think, and they are the ones who have the attention of management).

    A few MS staffers monitor this forum, but very little in the way of management with power to effect change.

    "MS" is a legal fiction, a corporation, it's only purpose in "life" is to MAKE MONEY. "They" do that very well. Some of their employees, real people, do feel shame and responsibility for the quality of the products they work on.

    The best place to complain about this problem is now the "Feedback" process MS has created in the last couple of years. Submit a new feedback, or vote and comment on an existing one (if one shows up as you are creating you subject line). AND copy the link and post it back here so the other people on this question can also more easily find it and vote for it. There is no guarantee of action, but it is our best hope. I have seen action taken on several "feedbacks" I've followed. Yes, the percentage is vanishingly small, but it is lightyears better than what we had before "feedback".

    And yes I remember QDOS.  Did you ever use QEMM? It did "windows" better than windows did with less resources.

    Absolutely!  Windows 10 is riddled with issues and I can't believe how there hasn't been a massive backlash against it.

    Any low end computer I've seen really struggles to run it because it makes the computer very unresponsive, where Windows is thrashing the hard drive processing updates, running compatrelrunner.exe and other nonsense right after the user turns it on and logs in.  Unless you have 4 cores and a SSD it runs like a complete pig due to very poor and unnecessary engineering decisions.  I tell people to turn their computer on and leave it 20 minutes to settle down.  Shockingly crap and amateur for a $1tn company!!!!!!!  Heads need to roll.

    Glad it helped.  I'm just learning to use Treesize, and like it very much so far.  Reminds me how much I relied on QDOS in the past.  Ever hear of it?

    Treesize does work.  Thanks for reminding me of the program.  I believe that I used this or some similar program years ago when I was trying to get the correct directory size in Windows.  I had forgotten about it.  This file size problem has been a bug in File Manager for many years, and given how long its been here, it is unlikely that Microsoft is going to fix it.  But it does seem that the problem has gotten worse in Windows 10 for some reason.
