How to clean up hidden junk files

Windows has built-in tools for this job, so if you don’t want to install a third-party app (more on that in a few), start here. Older versions of Windows have a tool called Disk Cleanup, available in virtually all versions of Windows. In the Windows search bar, look for ‘disk cleanup’ and launch the Disk Cleanup tool. You’ll have to select a disk drive to scan first. The tool will automatically scan that drive and present you with any old driver files or temporary junk files you can remove to clear space. You can repeat these steps for other drives as well.

Windows 10 and Windows 11 have an additional feature for cleaning up storage. It’s called Storage Sense, and it can automatically clean up junk files and hidden temporary files on a schedule. You can schedule Storage Sense to run every day, every week, or every month. You can also set Windows to automatically remove files from the Downloads folder if they haven’t been opened in a certain amount of time. Storage Sense can automatically clean the Recycle Bin on a schedule too.

Storage settings on modern Windows have some other handy features too. For example, you can see how much storage temporary files or downloads are taking up. You can also get cleanup recommendations from the system to clear old unused files or unusually large files. It’s handy when you’re trying to clean up a disk and aren’t sure where the heavy files are.

There’s also BleachBit, an open source app that’s purpose-built for cleaning junk files. It can run a deeper scan on folders that Windows tools ignore, and it provides you with better control over what gets deleted. If you want to remove ghost files leftover from previously uninstalled apps, BleachBit is a good fit.

Start by downloading and installing the Bleachbit app on your computer. Launch it once the setup is finished, and click the BleachBit icon in the corner to open the Preferences. We’ll add all the drives we want to scan in the Drives tab.

Now select the checkbox next to ‘Deep Scan’ and click ‘Preview.’ BleachBit will scan the drives and present you with a list of files that can be deleted. You can review the list, make sure there’s nothing on the list that is critical, and then click the ‘Clean’ icon to start the cleanup process. You’ll also see a list of apps with checkboxes next to them, which allow you to clean up apps with granular control. For example, you could clean up the thumbnail data or search History for File explorer without deleting anything else.

How to clean up old drivers

Old drivers that are no longer in use take up storage, so it’s a good idea to remove them. Plus, sometimes deleting drivers, especially graphic drivers, leaves behind ghost files which can mess with fresh installations or updates for the drivers. If you’re having trouble with graphic drivers, it’s always a good idea to clean up the previous installation and then reinstall the drivers. I also recommend cleaning up old drivers if you’re installing a new GPU.

Windows also has a built-in device manager where you can remove or disable old hardware drivers. Look for the ‘device manager’ in the Start menu and launch it. Under the View tab, select ‘Hidden Devices’ to see inactive or old device drivers. You might have to expand each category to see the faded icons of old, disused drivers. Right-click on a device and click ‘Uninstall Device’ to remove its drivers.

Both NVIDIA and AMD have dedicated tools for a fresh installation. They’re both simple utilities and work with a single click (no installation setup required). For the AMD Utility, you might have to boot into Safe Mode first. If the official tools don’t work, there is a third-party tool for removing old GPU drivers from any manufacturer called ‘Display Driver Uninstaller’ or DDU. It can remove driver packages from AMD, NVIDIA, and Intel.
