Storage Sense is the Windows 11 feature that reclaims disk space on its own. It removes temporary files that applications no longer need, empties the Recycle Bin on a schedule you choose, and can clear out your Downloads folder and release locally cached cloud files. Once configured, it keeps working quietly in the background.
It is off by default, and most of the confusion around it comes from the details: which drive it touches, what it will not delete, and why it sometimes does not run at all. This guide answers those questions and walks through the settings in order.
Storage Sense is a scheduled cleaner. Depending on how you configure it, it can do the following:
Three limits matter just as much as the abilities.
It only manages the system drive. Microsoft states plainly that Storage Sense works on the system drive, which holds Windows and is normally C:. Files on a second internal drive, an external disk, or a memory card are outside its reach, and there is a separate mechanism for those covered below.
It is off by default. Windows may turn it on by itself if your drive is critically low on space and you have never touched the setting, and it will notify you when it does. Otherwise you have to enable it.
It does not delete your personal files. The only personal folders it touches are the Recycle Bin and, if you explicitly configure it, Downloads. Cloud files are not deleted at all; they are marked online-only and come back when you open them, provided you have space and a connection.
Step 1. Open Settings and go to System > Storage.
Step 2. Set the Storage Sense switch to On. On a PC that has never been low on space, this is the first time the feature becomes active.
Step 3. Wait for Windows to finish scanning. The Storage page then shows a breakdown of what is consuming space, including a category for temporary files.
Step 4. Leave the page open for a moment. The categories and their sizes are the same data Storage Sense will act on, so it is worth reading them once before you set a schedule.
Step 1. On the same Storage page, select Storage Sense to open its settings.
Step 2. Under Run Storage Sense, choose how often it should run while you are signed in and online. The options are during low free disk space, every month, every week, every day, or never. "During low free disk space" is the mildest choice and the one Microsoft treats as the default behaviour.
Step 3. Under the Recycle Bin option, choose how long items may stay before they are removed: one day, fourteen days, thirty days, sixty days, or never. This is the setting people are most often surprised by. If you habitually restore files from the Recycle Bin a week after deleting them, set it to thirty days or to never, and empty the bin manually instead.
Step 4. Under the Downloads folder option, choose the same kind of period. Downloads is separate from the Recycle Bin and it is not enabled by default, so files there are safe unless you deliberately turn this on. If you keep installers or work files in Downloads, leave it set to never.
Step 5. Note what the low-space trigger actually means. The point at which Windows considers a drive to be low on space depends on the size of the disk and a minimum operating threshold, and the Storage page shows the capacity bar turning red when you reach it.
Step 1. Scroll to the cloud content section of the Storage Sense settings. It appears only when you are signed in to a cloud account such as OneDrive.
Step 2. Choose how long a file may remain unopened before it becomes online-only. Since Windows 11 version 22H2 the default is thirty days for OneDrive files.
Step 3. Understand what this setting does. It frees local disk space by removing the local copy while keeping the file in the cloud, where it remains listed in the folder. Opening it downloads it again, so nothing is permanently lost.
Step 4. Protect anything you need offline. Any file or folder marked Always keep on this device is exempt and is never managed by Storage Sense. Use that option for projects you work on without a reliable connection.
Step 1. To clean up immediately rather than waiting for the schedule, return to the Storage Sense settings and select Run Storage Sense now. The cleanup begins straight away.
Step 2. Wait for it to finish. It usually takes seconds, though it can take longer after a large Windows update.
Step 3. Go back to the Storage page and compare the categories. The temporary files figure is the one that normally drops, and it is often the largest single win on a machine that has never been cleaned.
Step 4. If you need a deeper manual clean, open the temporary files category on the Storage page. It lists each group separately, so you can remove individual items rather than everything at once.
Step 1. Remember that Storage Sense ignores every drive except the one holding Windows. A full data drive will not be cleaned by it no matter how the schedule is set.
Step 2. To enable the equivalent behaviour elsewhere, go to Settings > System > Storage > Advanced storage settings > Storage used on other drives, and turn on the option for the drive you want managed.
Step 3. Review what that setting will do before enabling it, because it applies your cleanup preferences to the selected drive.
Step 4. For drives that Storage Sense cannot handle, such as external disks, use a manual review of large files instead. Locating and deleting the biggest items is usually the fastest way to recover space on a data drive.
Step 1. Go to Settings > System > Storage and select Temporary files.
Step 2. Tick the entry for Previous Windows installation(s). This is the folder that holds your old copy of Windows after an upgrade, and it is frequently the largest item on the drive.
Step 3. Select Remove files and confirm.
Step 4. If the option is greyed out or the folder refuses to go, the usual cause is that the recovery window has not yet closed. Windows keeps the folder for a limited period after an upgrade so that you can roll back, and it removes it automatically once that period ends.
No. It removes temporary files and, on the schedule you choose, items in the Recycle Bin and the Downloads folder. Your Documents, Pictures, and Desktop folders are not managed by it.
No, it is off by default. Windows may enable it when your drive is critically low on space and you have never interacted with the setting, and it notifies you when that happens.
Microsoft notes that it cannot run unless you are signed in and online for more than ten minutes. A machine that is frequently shut down, or left at the sign-in screen, gives it no opportunity to work.
Not by default. Storage Sense manages the system drive only. To apply similar handling to another drive, use Advanced storage settings and the option for storage used on other drives.
Only if you turn that option on yourself. It is separate from the Recycle Bin setting and is not enabled by default, so Downloads is untouched unless you choose a retention period for it.
Right-click the file or folder and select Always keep on this device. Files marked that way are exempt from Storage Sense, and the cloud content setting can also be set to never if you prefer to manage it yourself.
Storage Sense keeps a drive tidy, but a cleanup is not a backup. It removes temporary files and cached copies, and it has no way to restore a document you deleted last month. Keep an image as well. Qiling Disk Master handles both the backup and the restore.
Step 1. Install and open Qiling Disk Master. On the home screen, open "Backup and Recovery" and choose "System Backup". This option automatically includes Windows and the hidden boot partitions, so you do not have to select them one by one.

Step 2. Check the source. The disk where Windows is installed and its system partitions are already ticked for you. If you only need your personal documents, run a separate "File Backup" task instead.

Step 3. Click the destination box and choose where the image should be saved. Use an external HDD or SSD, a NAS, or any drive other than the one Windows is installed on, and make sure it has enough free space.

Step 4. Review the task summary and click "Proceed". Wait until the progress bar reaches 100%. Do not unplug the drive or turn off the PC while the backup is running.

Step 1. Open Qiling Disk Master again, go to "Backup and Recovery", and select the recovery option. Your backup images are listed, so pick the one you created before the changes began.

Step 2. Choose the target disk or partition. Normally you restore to the original system disk. If the drive was replaced, select the new disk instead, and the restore rebuilds Windows together with its boot partitions.

Step 3. Preview the restore plan, click "Proceed", and confirm the warning. The PC restarts to finish the job, and Windows comes back exactly as it was on the day the image was created, with your files and programs intact.

Storage Sense is a scheduled cleaner that removes temporary files, empties the Recycle Bin after the period you choose, can clear the Downloads folder, and can make inactive cloud files online-only. It is off by default and it manages the system drive only, so a second internal drive or an external disk needs the Advanced storage settings instead. Two settings deserve attention before you enable it: the Recycle Bin retention period, which surprises people who restore files days later, and the Downloads folder, which stays untouched unless you deliberately switch it on. Run it once manually to see how much it recovers, and keep a real backup alongside it, because a cleanup cannot recover anything.
