Windows 10: Windows 10 - radical discrepancy in disk usage values

I've consistently noticed that there is such a vast difference between the disk usage calculation reported in the Properties dialog box and what I know to be the actual disk usage - confirmed by a utility that I use, TreeSize. See below:





On the left side, Windows 10 reports only 21.2 Gb in the Documents folder on D:

On the right side, TreeSize reports 275 Gb in the Documents folder on D: - which is accurate.


Why?


Thank you in advance for your response.

I suggest you to try the below steps and check if it helps.

Step 1: First of all, take a note of the processes or applications that is running when the computer runs with high disk usage. Also, we need to find the applications that are running at startup.

Follow the steps to check for the processes under Task Manager:

• Press Ctrl+Shift+Esc to open Task Manager.
  
• Click on Processes tab. Check if any of the processes consumes high memory usage.

Bad sectors on the hard drive can be a cause for high disk usage.

Check which process is utilizing the Hard Disk on Windows 8.1, you may try the following steps.

• Open Task Manager and click on
  Details tab.
• Right click the columns headers and click "Select Columns".
• From the "Select Columns" window, check: I/O Reads, I/O Writes, I/O read bytes, I/O write bytes and then click
  OK.
• Now the columns will be added to the view and will display how much each process is utilizing from the hard disk.
• Sort by I/O read bytes or I/O write bytes by clicking on the column header to see which process is utilizing the Hard Drive most.
