Start with things you recognize.
Delete old downloads, empty the recycle bin, remove apps you no longer use, clean up large videos and duplicate files, move personal files elsewhere, and use your computer's built-in storage cleanup tools. Leave unfamiliar system folders alone.
When your storage gets nearly full, the symptoms can show up in weird places.
Apps may stop updating. Files may fail to save. Your computer may feel slower. Updates may fail. Programs can even start crashing.
The tempting reaction is to start deleting anything that looks large.
Don't.
The safer approach is to clean up personal files and programs you understand first, then use built-in tools to handle temporary system data.
Know what kind of space you're trying to recover.
8 things to clean up
Empty the recycle bin or trash.
Files you delete often continue using storage until the recycle bin or trash is emptied.
Open it first and look through the contents before permanently deleting anything.
If you're sure you no longer need those files, empty the bin.
Clean out your Downloads folder.
Downloads folders are storage graveyards.
Old PDFs, installers, ZIP files, images, documents, and random files can quietly pile up for years.
Sort the folder by size or date and start with things you clearly recognize.
Look for large videos and recordings.
Video files can eat enormous amounts of storage compared with normal documents and photos.
Check folders where you save screen recordings, downloaded videos, camera files, edited clips, meeting recordings, or creator content.
Delete what you truly don't need or move important files to another storage location.
Uninstall programs you don't use.
Open your computer's installed apps or programs list.
Look for games, utilities, trial software, old applications, or tools you haven't used in months.
Use the normal uninstall process rather than simply deleting the program's folder.
Use the built-in storage cleanup tools.
Modern computers include storage-management tools that can identify temporary files, update leftovers, caches, and other cleanup candidates.
These tools are usually safer than digging through system folders manually.
Review the categories before approving deletion, especially anything involving Downloads or personal files.
Find duplicate and forgotten personal files.
Multiple copies of the same photo, exported document, downloaded PDF, or video can quietly add up.
Look through common personal folders like:
Documents, Desktop, Pictures, Videos, and Downloads.
Sort by size when possible. The biggest files usually give you the fastest wins.
Don't randomly delete system folders.
Avoid manually deleting unfamiliar files from folders related to Windows, Program Files, system libraries, drivers, hidden operating-system data, or application data just because something inside looks large. A storage-cleanup tool or proper uninstall process is much safer.
Move large files you want to keep.
Not everything taking up space needs to be deleted.
Important photos, videos, archives, and old projects can be moved to another appropriate location.
Depending on what you use, that may be an external drive, another computer, network storage, or a cloud-storage service.
Restart and check your storage again.
After cleaning things up, restart the computer.
Then return to your storage settings and see how much space you recovered.
A restart can also allow temporary files, updates, and background processes to finish cleaning themselves up.
Now we find the space hog.
If you've completed the obvious cleanup and you're still running out of storage, look at the categories in your computer's storage settings.
- Are installed apps taking most of the space?
- Are videos or photos unusually large?
- Is your Downloads folder still huge?
- Is cloud storage keeping local copies of everything?
- Are multiple user accounts storing files on the computer?
- Is “System” or “Other” using far more storage than expected?
- Do you simply have a very small internal drive for the amount of data you keep?
At that point, the best solution may be reorganizing your storage rather than continuing to delete random files.
