  1. Wrong file size in Properties


    Hello, I have a 4GB folder that is reported as 4TB in file explorer properties. I see this was an issue first reported in 2018. I'm running widows 10 pro 21H2.I've run several scans and fixed corrupted files as recommended in earlier posts with no luck.Is this really still a bug in one of windows' most basic and oldest features? Thanks!

    :)

    File Explorer shows wrong folder size

    I think the issue is solved. The problem of File Explorer Properties showing greatly reduced folder size was present in my Documents folder and my two most used folders under Documents. Looking at the TLPD results I noticed that along with the 17,000 results from the folders "C:\Windows\SoftwareDistribution\Download" and "C:\Users\[me]\AppData", there were about 4 results from each of these two most used folders. I went to those files in the first folder and shortened the names to well below 255 characters. Then File Explorer Properties showed the correct folder size (that is to say the same size as Tree Size Free shows), but Documents folder size was still wrong. Then I went to the second of these two folders and carefully did the same fix. Now File Explorer Properties folder size is correct for this folder and is correct for Documents.

    Documents and both of these folders are present in my Quick access. Before this fix, I noticed that if I checked folder size in File Explorer, I got the wrong size whether I used the left pane under Quick access, or the right pane; but if I hovered over the folder in question in the right pane, the pop-up showed the correct size. I don't know if either of these are pertinent to the original problem.

    Strangely, the wrong folder size problem never appeared in the two folders for which TLPD returned 99% of it's results: "C:\Windows\SoftwareDistribution\Download" and "C:\Users\[me]\AppData". File Explorer Properties and Tree Size Free always agreed.

    So I guess that if you want your File Explorer Properties to work correctly, you must run TLPD occasionally and rename any long file names under Documents; or carefully avoid long names.

    Any suggestions on how to avoid this problem or an easier fix would be appreciated.

    Thanks for everybody's help.

  3. Properties shows wrong size for files and folder

    I went through both methods (thanks alot for the help BTW) and retested the same pictures drive again, with both methods again

    Method 1 - right clicking on the folder...selecting properties, and reading the size on disk it reports

    Method 2 - opening up the folder, clicking inside the search bar and selecting *.* which shows every file and folder inside + all subdirectories. Confirmed theres no "grouping" its all just listed together. Select all files (control A) then right click and
    select properties...and reading the size on disk it reports

    Same results Im afraid. I retested another folder on a physically different hard drive using the same test - and also came up with ridiculously contradicting claims on how much data is in there

    Interesting hey Test 1 = 142Gig VS 386Gig

    Test 2 on a seperate HDD (physically seperate drive) 669Gig VS 184Gig
