What CMD Commands Can I Use to Clean My Computer?

Below are some common CMD commands for cleaning your computer, organized by system type:

Windows System

• Disk Cleanup:
  • cleanmgr: This one’s a lifesaver and the go-to for most folks. Just type “cleanmgr” in the Command Prompt and hit Enter. It’ll open up the Disk Cleanup utility, which scans for junk files. Pick the drive you want to clean, then let it do its thing. You’ll see a list of file types—choose what you want to toss and click “OK.”
• Clear Temporary Files:
  • cd %temp% & del /q /f /s *: First, type “cd %temp%” to get to the Temp folder. After that, run “del /q /f /s *” to clear it out. “/q” keeps it quiet (no prompts), “/f” forces the delete, and “/s” cleans subdirectories too.
  • del /q /f /s C:\Windows\Temp*: This one’s straightforward—it dumps everything in that Temp folder.
• System File Check and Repair:
  • sfc /scannow: SFC stands for System File Checker. This command checks for system file issues and fixes them. If something’s up with your Windows files, this should sort it out.
  • dism /online /cleanup-image /restorehealth: DISM is another handy tool. It’s like SFC but for Windows images. It’s good to run it before SFC to fix deeper issues.
• Clear DNS Cache:
  • ipconfig /flushdns: If your internet’s been funky, try this. It clears out old DNS entries, making your PC fetch fresh ones.
• Uninstall Unnecessary Programs:
  • wmic product get name: Shows a list of everything installed on your computer.
  • wmic product where “name=’ProgramName'” call uninstall: Replace “ProgramName” with the name of the annoying program you want gone.
• Manage Startup Programs:
  • msconfig: Type this and you’ll get the System Configuration window. Head to the Startup tab and uncheck the stuff you don’t need at launch.
• Hard Drive Optimization:
  • chkdsk /f: Gives your hard drive a check-up. It looks for issues and fixes them. If the drive’s in use, it’ll schedule a check for the next restart. Type “Y” to confirm, then restart.

macOS System

• Clear System Cache:
  • sudo rm -rf /Library/Caches/*: Clears out system-wide caches.
  • sudo rm -rf ~/Library/Caches/*: This handles your personal caches.
• Delete Application Log Files:
  • sudo rm -rf /var/log/*.gz and sudo rm -rf /var/log/*.bz2: These get rid of old log files that just take up space.
• Remove Unnecessary Language Files:
  • sudo find / -name “*.lproj” -not -name “en.lproj” -exec rm -rf {} +: This command zaps language files you don’t need, keeping only the ones in English (or another preferred language).
• Empty the Trash:
  • rm -rf ~/.Trash/*: Sometimes the Trash needs a good kick. This command clears it out instantly.
• Find and Delete Large Files:
  • find ~ -type f -size +500M: Finds files bigger than 500 MB. If you find stuff you don’t need, delete it with rm -rf [file_path].
• Free Up Disk Space by Deleting Old Downloads:
  • find ~/Downloads -type f -mtime +30 -exec rm -rf {} +: Gets rid of downloads older than 30 days. Keeps the recent stuff.
• Free Up RAM and Disk Cache:
  • sudo purge: Clears out RAM and cache. It’s a good idea to close everything before running this.

A heads-up: When using CMD commands, be careful. Some of them can delete stuff permanently. Always know what you’re typing and consider backing up important files. And definitely steer clear of commands like “rm -rf /*” or messing with critical directories. Double-check before you hit Enter, especially if you’re using “sudo.”

Alright folks, let’s dive into cleaning up our computers using the good ol’ Command Prompt in Windows. Trust me, these commands can help you get rid of junk files, clear out temp ones, and make your system run a tad smoother. Here’s what you need to know:

First things first, we’ve gotta open Command Prompt and make sure we’re running it as the boss, aka administrator. Here’s the drill: Hit those Windows + S keys to pop open the search bar, type in cmd, give the right-click on Command Prompt, and smack Run as administrator.

Now, let’s talk trash. The Disk Cleanup utility is where we start clearing out the mess without breaking a sweat. Just run this little command and it’ll ask you which drive you want to tidy up:

Want to clean up a specific drive? Swap the C here with whichever letter matches your drive:

/D C

Feeling fancy and want to do a bit more than just basic cleaning? You can set up what files to nuke for good with this:

/sageset:1

Once you’ve made your picks, run the show with:

/sagerun:1

That’ll take care of the cleanup based on your wishlist.

Now onto those sneaky temporary files, which just love gobbling up your space. You can peek at them by typing:

%temp%\\

Or knock ’em out directly without asking for confirmation:

%temp%\\*.* /s /q

Don’t overlook the prefetch files. They speed up apps but can overstay their welcome. Take a look using:

C:\\Windows\\prefetch\\

And clean them out with:

C:\\Windows\\prefetch\\*.*/s/q

Here’s where things get fun: Defragmenting your hard disk. It\’s like rearranging your bookshelf for better feng shui, and it’s a good move for those mechanical hard drives. Fire up this command for a specific drive, like C:

C:

Feeling a bit bogged down with connectivity glitches? Flush those DNS cache cobwebs with:

/flushdns

Had a bad day and your system’s acting up? Let DISM be your guardian angel. Check the health of your system:

/Online /Cleanup-Image /CheckHealth

And if it’s doctors orders, restore it with:

/Online /Cleanup-Image /RestoreHealth

Now, if you\’re feeling like James Bond and need to wipe an entire disk—make sure you back up first, seriously—here’s your mission. Start up Diskpart:

Take stock of all connected disks:

disk

Pick your victim by selecting the disk number, like so:

disk

And wipe it all, no going back now:

all

So, there you have it, these CMD commands are your go-to for sweeping clean those nooks and crannies in your PC, boosting performance, and keeping your storage in check. Happy cleaning!
