If you are using your computer and you notice that Hard drive shows high space utilization even if you only have a few applications installed on your computer, then you’ve come to the right place as this post will guide you on what you can do to sort this problem. Upon noticing the odd state of your hard drive and you check the actual volume that’s occupied by the apps in your drive and you see that they are not really occupying a lot of space. This kind of issue could indicate that your hard drive is not showing the correct value for the free storage space of the drive-in your Windows 10 computer. This kind of problem could be passed off as a system bug, however, it could also be a serious problem. In fact, as you are aware, there are hidden folders and files in your computer that could be occupying space and since most of them are associated with system applications, you might not realize it unless you thoroughly check the folders.

The most common causes of the issue are as follows:

1. The system information folder might be utilizing a lot of space. If you wonder where the information for the system restore points is stored, they are stored in the system information folder which in turn is stored in the drive as a hidden file.
2. An issue with system maintenance could cause the problem.
3. Malware or some other software might have created an undetectable hidden file.
4. Space could be occupied by the trashbin folder.
5. These hidden files could occupy significant space in the folder, thus slowing down the system and impacting its performance. If you face this issue, try our suggestions and see if they help you.
6. Run ChkDsk
7. Clear all Junk files
8. Reduce the space occupied by the system restore points
9. Run the System Maintenance troubleshooter

Option 1 – Run CHKDSK utility to check the drive for errors

When it comes to some issues concerning the hard drive or removable devices, there is a utility in Windows that might help which is called “chkdsk”. To use it, follow the steps below.

• Tap the Win + S keys to open the Search box.
• Then type “command prompt” in the field and from the search results that appear, right-click on Command Prompt and select “Run as administrator”.
• After opening an elevated command prompt, copy and paste the following command and hit Enter:

CHKDSK [volume [[path] filename]] [/F] [/V] [/R] [/X] [/C] [: size]]

Note: In the command given above, “[/F]” will try to fix the system errors while “[/R]” will be the one to fix the bad sectors.

• Now if you are prompted to run CHKDSK after your reboot your PC, just tap Y and reboot your PC.
• If CHKDSK is not able to find any errors, tap the Win + E keys and navigate the access window. From there, right-click on the concerned drive and click on Properties.
• After opening Properties, click on the tab Tools and then click on the “Check” button under the Error-checking section.
• Wait until the process is completed and then restart your computer.

Option 2 – Try to delete the temporary files

The error could be caused by some temporary or junk files in your computer and so you need to clear them up to fix the problem. You can achieve that using the Storage Sense feature.

• Open Setting > System > Storage from the WinX Menu.
• From there, you will see a list of all the local and connected storage devices along with the details on the free space. Make sure that Storage Sense is on.
• Next, find a link that says “Free Up Space” and click it to open.
• After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space: 
  • Windows Upgrade Log Files
  • The system created Windows Error Reporting Files
  • Thumbnails
  • Temporary Internet Files
  • Previous Windows Installation Files
  • Delivery Optimisation Files
  • DirectX Shader Cache
• Choose the files you want to get rid of and then click on the remove files option. Note that you’ll have an idea of the total size as you select any of the junk files listed above.
• Now go to the “Free Up Space Now” section and click the Clean Now button. This will get rid of all the temporary or junk files in your computer and should hopefully fix the error.

Option 3 – Try to reduce the space occupied by the system restore points

In case you don’t know, system restore points actually occupy a significant space in your computer which is stored in the System Information folder. Thus, you need to check the size of this folder and unhide the folders and files and then click on the folder. The size of the folder should be displayed in the right pane of the window. To fix the storage space problem, you could delete all the old System Restore Points as well as Previous versions of files or you could also restrict the disk usage of the System Restore points.

Option 4 – Try to run the System Maintenance troubleshooter

The problem could also be caused by the System Maintenance and to fix it, you have to run the System Maintenance troubleshooter by following these steps:

• In the Windows Search bar, type “control panel” and double click on Control Panel from the search results.
• Next, go to this path: Control PanelAll Control Panel ItemsTroubleshootingSystem and Security.
• After that, click on the System Maintenance troubleshooter to run it.
• Once the process is completed, restart your computer.

Recent Windows updates have been slowly but surely moved a lot of control panel features into settings. This indicates that in the long term goal is probably to get rid of the control panel altogether. No matter how the setting app is easy to use and good there are still things in the control panel that we need and we will still need until they are all moved in the setting application. There are several ways to open and get to the control panel from run dialog to shortcut keys but one perhaps more convenient and easiest way is to just simply have in file explorer right beside hard drives double click away. In order to place the control panel icon inside file explorer, we will need the help of our old friend: the registry editor. As always playing with the registry editor can cause some instability and it is always a smart thing to back up it first before attempting any kind of edits.

Registry editor adding a key

To open registry editor press ⊞ WINDOWS + R to open the run dialog and inside type in REGEDIT followed by ENTER Once the registry editor is opened locate the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\MyComputer Right-click on the NameSpace folder on the left navigation pane and then select New > Key Rename the key with {21EC2020-3AEA-1069-A2DD-08002B30309D} (This CLSID code will add access to the Category view of the Windows 10 Control Panel) or with {26EE0668-A00A-44D7-9371-BEB064C98683} (This CLSID code will add access to the large icons view of the Windows 10 Control Panel) Save and exit the registry editor Now when opened, file explorer will show a control panel icon for easy access.

By default inside Windows 11 in File Explorer, once the file is selected, the small check box will appear beside it on left indicating visually that the file is selected. Older users will remember this feature from old Windows Vista and the feature itself is great if you are on some sort of touch device and need to select multiple files. However, if you are working on a computer with a keyboard and mouse this feature might annoy you and seem like something that is not needed. Like many things inside Windows 11 this feature also can be customized and turned OFF if you do not want it. In this guide, we will see how to turn these boxes off. Microsoft has somewhat hidden this feature but luckily it is not difficult to find it if you know where to look.

Turning check boxes OFF

1. Open File Explorer (if you do not have an icon on your Taskbar, right-click on the Start button and select File Explorer from the menu)
2. Click on View on the top toolbar
3. Select Show
4. Uncheck Item Check Boxes

That is everything that needs to be done, after the checkbox is unchecked all check boxes from File Explorer will disappear. If you wish to turn boxes back ON, just follow the steps and check the box beside Item Check Boxes.

If you got an error message saying, “Folder Redirection Failed, Failed to build the list of regular subfolders, Access is Denied” after you configured a new Group Policy Object or GPO which redirects User folders to a new network share or when you click on Reset default location under the Windows File Explorer or Folder Options, then you’ve come to the right place as this post will show you how to resolve this kind of error on your Windows 10 computer. Follow the given options below carefully to fix the “Folder Redirection Failed” error.

Option 1 – Take Ownership of the folder

If you are not able to access the folder could be one of the reasons why you’re getting the “Folder Redirection Failed” error and so you need to take ownership of the folder to resolve the problem. Before you proceed, make sure that your account is an admin account.

• First, locate the concerned folder and right-click on it then select Properties.
• Next, click on the Edit button in the Properties window and click OK to confirm if you got a User Account Control elevation request.
• After that, select user/group from the permission windows or click on the Add button to add another user or group. It would be best if you add “Everyone” to give permission.
• Then check “Full Control” under the “Allow” column to assign full access rights control permissions.
• Now edit the permission to Full Control for “Everyone”.
• Click OK to save the changes made and then exit.

Option 2 – Try to add Authenticated Users or Domain Computers

Make sure that the Folder Redirection group policy removal option is set to “Redirect the folder back to the user profile location when the policy is removed” when using the Folder Redirection. After that, you have to add Authenticated Users group with the “Read” permissions on the Group Policy Objects or GPOs. And if the Domain computers are part of the group of “Authenticated Users”. Note that by default, the “Authenticated Users” have these permissions on any new Group Policy Objects or GPOs. Once again, you have to add just “Read” permissions and not “Apply Group Policy” for “Authenticated Users”. Furthermore, to fix the “Failed to build the list of regular subfolders” errors, here are some options that could help.

Option a – Try to clear disk space

You might have to check if your disk is running out of space because if it is, then it will fail to create a list abruptly. And so you need to free up some disk space. You can either check on the files manually especially if you tend to keep your files at random places in your disk drive.

Option b – Find the Target route

You need to find the target route of the folder and then restore it if you are getting the “Failed to build the list of regular subdirectories” when you try to relocate the folder to the original location.

Option c – Try to change Ownership/Reset Defaults for all the User folders

If the “Failed to build the list of regular subdirectories” error pops up when you are trying to move a large number of files from one location to another, then you need to change the ownership of the folders as pointed out earlier.
