Of class, this takes up space, which is what the hibernation file is for. Depending on your hard drive size, the hibernation file is likely several gigabytes or more than.
If y'all don't use hibernation and want to disable it, you tin easily do then via the Command Prompt. Note that you shouldn't just delete hiberfil.sys, as Windows will recreate it again.
Right-click on the Start button or press Win + Ten, then open up a Command Prompt (Admin) or Windows PowerShell (Admin) window from the resulting menu. Type the following command to disable hibernation:
powercfg.exe /hibernate off That'due south all it takes to disable hibernation. Windows should delete hiberfil.sys on its own when you do this; feel gratuitous to delete it after if not. Annotation that disabling hide mode volition too forbid your calculator from using fast startup in Windows x. However, this isn't much of a loss, as this characteristic is known to cause slow kick times and other problems.
2. Windows Temp Folder
Location: C:\Windows\Temp
As you'd guess from the name, Windows temporary files aren't of import beyond their initial use. The files and folders inside comprise info that Windows used at one time, only doesn't need anymore.
Instead of cleaning via Disk Cleanup. you can visit this folder and delete its contents manually, if you want. Simply press Ctrl + A to select everything inside, then hit Delete. Windows might give you an fault about a couple of items when y'all do this—only ignore those and articulate everything else.
three. The Recycle Bin
Location: shell:RecycleBinFolder
The Recycle Bin is a special folder—while it appears under your C:\ drive, this is protected by Windows and you don't need to admission information technology that way. Whenever you delete a file on your system, Windows sends it to the Recycle Bin. This is a special identify where deleted files are kept until you permanently delete or restore them.
While this might be obvious to you lot, we're including it in example some aren't aware. It's easy to forget that gigabytes of old data can sit in your Recycle Bin.
You can admission the Recycle Bin through the shortcut on your desktop. If you don't see that, blazon shell:RecycleBinFolder into File Explorer's navigation bar. Once here, you lot'll encounter everything you've deleted recently.

We don't recommend this, because the Recycle Bin gives you a 2d chance in case of an adventitious deletion. Similarly, Display delete confirmation dialog will crave an extra pace whenever y'all erase a file.
4. Windows.erstwhile Folder
Location: C:\Windows.old
Whenever you lot upgrade your version of Windows, the system keeps a re-create of your prior files called Windows.old. This folder essentially holds everything that fabricated upwards your old installation, in case something didn't transfer correctly.

Information technology won't delete if yous endeavor to go through the File Explorer, and then type Disk Cleanup into the Starting time Menu and launch the tool as described earlier.
Click Clean up system files at the bottom of the window and allow the utility do another scan. Once that's done, look for the Previous Windows installation(s) and delete it using this tool.
Obviously, removing these files makes it harder to recover data in instance of an upshot. After performing a Windows upgrade (even merely to the latest version of Windows 10) nosotros advise y'all to hold onto this folder until you're sure everything is working properly.
5. Downloaded Program Files
Location: C:\Windows\Downloaded Plan Files
This folder's name is a fleck disruptive. Information technology actually holds files used by Net Explorer's ActiveX controls and Java applets, so if you lot utilize the same feature on a website, y'all don't have to download information technology twice.
In issue, this folder is useless today. ActiveX is an extremely outdated technology that'south total of security holes, and Java is about-extinct on today's web. Cyberspace Explorer is the simply browser that supports ActiveX, and you'll probably only run across it on ancient corporate websites (if e'er) at present.
Well-nigh domicile users don't employ IE anymore, let alone ActiveX. Your Downloaded Program Files folder might already be empty, but feel free to clean out its contents if it's not.
vi. LiveKernelReports
Location: C:\Windows\LiveKernelReports

If your computer runs into an issue, you tin can clarify the contents of these files to commencement troubleshooting your problem.
Whatsoever huge files ending with the DMP file extension in this folder are safe to delete. Similar the higher up locations, though, we recommend using Disk Cleanup instead of deleting the file yourself.
When Windows crashes or yous have other major reckoner issues, don't delete these dump files correct abroad. You tin use a plan like WhoCrashed to get more info from them.
7. Rempl Binder
Location: C:\Programme Files\rempl
While the Rempl folder isn't large, you lot might exist surprised when you meet it appear on your system. It contains several modest files, and you might even notice a few Job Manager processes connected to information technology.
This folder is continued to Windows 10 update delivery. It includes "reliability improvements" to help make Windows ten updates become smoothly and iron out compatibility issues.
Then can y'all delete the Rempl folder? There are seemingly no adverse effects from doing so. Yet, since information technology only takes upwards a few megabytes and tin make Windows upgrades less frustrating, it'south all-time to keep it effectually.
These Windows Folders Tin Be Deleted
It takes a bit of looking effectually, but Windows holds plenty of files and folders that aren't necessary. Remember that your computer does a pretty good chore of keeping itself clean, so you don't have to obsessively remove the contents of these folders unless you're really depression on disk infinite.
Running the Deejay Cleanup tool one time or twice a calendar month should do enough to proceed the cruft away. If yous yet demand to free up a lot of infinite, try uninstalling some unnecessary Windows software.
