Windows 10: File Explorer shows wrong folder size

Recently I noticed that in File Explorer when I right click on a folder and click Properties, the folder size is sometimes shown much smaller than the correct size. For example, in File Explorer, Documents shows as 30 MB (repeat 30 MB), while in Tree Size Free the correct size of 24 GB (repeat 24 GB) shows. Within Documents I have about 75 sub-folders. The same issue occurs only in some of the folders at this level: apparently folders I frequently access have the same issue, while infrequently accessed folders show the correct size in File Explorer.

Also, in File Explorer Properties, all folders (Documents, C:, D:, including all sub-folders) show a filled in box at Read-only; and I don't believe that was the case before, I certainly never set them as read only in the past. All files Properties, however, show a blank box at read only.

Otherwise all folder and file operations seem to be working correctly; I can open, change name, and close all folders; and add, delete, or change all files within folders. So I guess all the folders indicated as Read-only are not actually Read-only.

Perhaps this is a quirk I should just ignore; but I am concerned that this might indicate a bigger problem than is apparent, and it is awkward to have to open Tree Size every time I want to check a folder's size. If there is a relatively easy fix I would do it.

Thinking back to recent things I have done that could possibly have caused this: I have done a system image of C: drive onto the D: drive, then realized I should instead turn on Windows automatic backup to do the same thing and did so, then downloaded Macrium Reflect to put a C: drive system image onto a CD. Apparently both system images also created restore points.

Thanks for any help anyone can provide.

File Explorer way off in showing folder size

File Explorer can only count the size of the files in folders that you have permissions for. TreeSize Free when run as administrator can see everything.

From the sizes listed in your screenshots, it would appear you only have permissions for the D:\Caroline 2019.02.06\Documents folder.

 

Windows File Explorer Not Showing Folder Size

Need Help,

Windows File Explorer Not Showing Folder Size. Its very difficult to identify big size folder.

 

Win10 pro 1803 update shows wrong folder sizes

Windows 10 pro 1803 update shows totally wrong folder sizes. same problem is reported by other users here. Same problem is posted here by other users too, as early as May 2018. I wonder what has been done about it by Microsoft.

The problem is two fold

1. If you select a folder directly from left pane of the file explorer by right clicking it, it shows totally wrong total size.

2. If you left click the folder in the left pane to see listing of subfolders and files in it - in the right pane, and then select everything in the right pane by control +A and then right clicking it to see total size of all folders and filess, the folder
that is just underneath the cursor is selected and shown at the top of the box that opens to show the total size. Here too it shows wrong size information. I wonder why windows selects name of the folder underneath the cursor to show at top of the box even
when you select all folders.

I hope Microsoft will take care of this on urgent basis and not sleep over it.

I have been using Windows since windows 3.11. Every time there is a upgrade, some old problems disappear and totally new ones crop up in the most unexpected places.

PLEASE HELP. thanks
