How to Get More Storage on PC: Step-by-Step Guide in 2026

Running out of storage on your PC is frustrating. You open a file, download something new, or try to install a game and suddenly your computer tells you there is no space left. The good news is that you have several ways to fix this, both free and paid. This guide walks you through every option so you can pick what works best for your situation.

Let us get to the point fast: you can get more storage on your PC by deleting junk files, upgrading your internal drive, adding an external drive, using cloud storage, or expanding with an SD card or USB drive. Most people need a mix of two or three of these.

Why Your PC Runs Out of Storage (And Why It Gets Worse Over Time)

Your PC fills up faster than you think. Windows itself takes up around 20 to 30 GB. Add your apps, browser cache, temporary files, game saves, downloads, and update files, and you are eating through hundreds of gigabytes without even noticing.

Common culprits that quietly steal your space include Windows Update files sitting in a folder called WinSxS, hibernation files, old system restore points, browser cache that grows over months, and large files you downloaded and forgot about.

Before spending money on hardware, it helps to understand exactly how full you are and what is eating your space.

Step 1: Check Your Current Storage Usage

Go to Settings > System > Storage. Windows gives you a breakdown showing what is using space: apps, temporary files, documents, and more. This is your starting point. If you are at 85% or more, your PC may already be slowing down because Windows needs free space to work properly.

You can also open File Explorer, right-click your C: drive, and click Properties to see a simple pie chart of used vs. free space.

Free Methods to Get More Storage on PC

These cost nothing and should always be your first move.

Run Windows Storage Sense

Storage Sense is a built-in tool that automatically deletes files you no longer need.

Go to Settings > System > Storage > Storage Sense and turn it on. You can configure it to run automatically or trigger it manually. It removes temporary files, empties the Recycle Bin, and clears old Windows Update files.

To run it manually right now, scroll down and click Run Storage Sense now. Many people free up 5 to 15 GB on their first run without deleting a single file they actually care about.

Run Disk Cleanup

Disk Cleanup is the older but still powerful version. Search for it in the Start menu.

Select your C: drive, let it scan, then check everything including Previous Windows installations if you recently upgraded. Click Clean up system files for the deeper scan. This tool has been around since Windows 98 and still works well in 2026.

Delete or Move Your Downloads Folder

Most people never clean their Downloads folder. Open it and sort by size. You will likely find old installers, ZIP files you already extracted, and large video files you watched once. Delete what you do not need. Move the rest to an external drive.

Uninstall Apps You Do Not Use

Go to Settings > Apps > Installed Apps. Sort by size. You may have games or software using 5 to 20 GB that you have not touched in a year. Uninstall them. You can always reinstall later.

Clear Browser Cache

Your browser stores copies of websites to load them faster. Over time this cache grows to several gigabytes. In Chrome, go to Settings > Privacy and Security > Clear browsing data and clear cached images and files. In Edge, go to Settings > Privacy, search, and services > Clear browsing data now.

Move Files to an External Drive or Cloud

If you have photos, videos, or documents you want to keep but rarely access, move them off your main drive. This is one of the fastest ways to free up space without deleting anything permanent.

Disable Hibernation

Hibernation saves your RAM contents to disk so your PC can resume fast. The file (hiberfil.sys) can be several gigabytes. If you do not use hibernation, open Command Prompt as Administrator and run:

powercfg /h off

This deletes the hibernation file and frees that space instantly.

Compress Files and Folders

Windows has built-in compression. Right-click a folder, click Properties > Advanced > Compress contents to save disk space. This works best on documents and files you keep but rarely access. It is not ideal for media files since they are already compressed.

Paid Methods to Get More Storage on PC

When free methods are not enough, it is time to invest in more physical storage. This is where you get a real, permanent solution.

Upgrade Your Internal SSD

This is the best long-term fix. Replacing your main drive with a larger SSD gives your whole PC more breathing room and often makes it faster too.

What to buy: Most modern PCs use either a 2.5-inch SATA SSD or an M.2 NVMe SSD. Check your PC or laptop manual to find out which slot you have. M.2 NVMe drives are faster but you need the right slot.

In 2026, a 1TB SSD costs around $50 to $80. A 2TB SSD runs $90 to $150. These are excellent values compared to a few years ago.

How to upgrade: You do not need to reinstall Windows. Use cloning software like Macrium Reflect Free to copy your existing drive to the new one, then swap the drives. It takes about an hour start to finish.

Drive Type	Typical Speed	Best For
SATA SSD	500 MB/s	Laptops, older desktops
M.2 NVMe SSD	3,000 to 7,000 MB/s	Modern desktops, thin laptops
HDD	100 to 150 MB/s	Cheap bulk storage only

Add a Second Internal Drive

If your desktop PC has an extra drive bay, you can add a second drive without replacing anything. This is common in gaming PCs where people use a fast SSD for Windows and games, and a large HDD for media and backups.

A 4TB HDD costs around $70. A 2TB SSD is around $100. You just plug it in, format it in Windows, and start using it.

Laptops usually do not have space for a second internal drive unless they have an optical drive bay you can swap out with a drive caddy.

Add an External Hard Drive or SSD

External drives are the simplest upgrade with no technical skill required. Plug it in via USB, and it shows up in File Explorer immediately.

External HDD: Good for backups, photos, and videos. A 4TB external HDD runs about $80 to $100. They are slower but cheap per gigabyte.

External SSD: Faster, more portable, and more durable. A 2TB portable SSD runs around $100 to $150. Great if you travel with files.

The downside to external drives is that they only work when plugged in. They are best for files you do not need every day.

Use Cloud Storage

Cloud storage keeps your files on remote servers. You access them through the internet. This frees up space on your local drive.

Options in 2026:

Service	Free Storage	Paid Plans
OneDrive	5 GB	100 GB for $2/month, 1 TB with Microsoft 365
Google Drive	15 GB	100 GB for $2.99/month
iCloud	5 GB	50 GB for $1/month
Dropbox	2 GB	2 TB for $9.99/month

OneDrive integrates tightly into Windows. You can enable Files On-Demand which shows your cloud files in File Explorer without downloading them all. Only files you open get downloaded. This is a smart way to keep your drive light while keeping access to everything.

For most users, OneDrive or Google Drive with a paid plan is the easiest and cheapest way to expand effective storage without any hardware.

Use a MicroSD Card or USB Flash Drive

If your laptop has a microSD slot or a spare USB port, you can expand storage cheaply.

A 256 GB microSD card costs around $20 to $30. A 512 GB USB flash drive runs about $30 to $50.

You can configure Windows to save new files, photos, and documents to these locations by going to Settings > System > Storage > Advanced storage settings > Where new content is saved.

The downside is speed. SD cards and flash drives are much slower than SSDs. Do not put your operating system or frequently used apps on them. They work best for photos, documents, and media you access occasionally.

How to Move Your Windows Page File and Temp Files

If you have added a second drive, you can move certain system files off your C: drive to free up space.

Move Temp files: Go to Settings > System > Storage > Temporary files and delete them regularly. You can also change the location of your user temp folder through System Properties > Advanced > Environment Variables, pointing TEMP and TMP to another drive.

Move the Page File: Right-click This PC > Properties > Advanced System Settings > Performance Settings > Advanced > Virtual Memory. Set the C: drive to no paging file and set a custom size on your second drive. This can recover several gigabytes.

How to Find Large Files Eating Your Space

Windows does not always make it obvious where your space went. Use these tools.

WinDirStat is a free program that shows a visual map of your hard drive, making it easy to spot the biggest folders and files at a glance. It is completely free and takes under a minute to scan. You can find it at windirstat.net.

TreeSize Free is another excellent option with a cleaner interface. Both tools are trusted by millions of users.

After scanning, look for any folder using an unexpected amount of space. Common surprises include old game installers in your Downloads folder, large database files from apps like Spotify, and massive log files created by software.

Choosing the Right Solution for Your Situation

Not every fix works for every person. Here is a quick guide.

Your Situation	Best Fix
Laptop, not technical	External SSD or cloud storage
Desktop with empty drive bay	Add second internal HDD or SSD
Laptop with M.2 slot available	Upgrade internal SSD
Have fast internet, travel a lot	Cloud storage
Budget under $30	MicroSD card or free up space first
Gaming PC needing more game storage	Add second NVMe or large SSD
Files piling up, no budget	Delete junk files and move to free cloud storage

What NOT to Do

A few things people try that either do not help or cause problems.

Do not delete system files manually. Deleting files in the Windows folder or System32 can break your PC. Stick to Disk Cleanup and Storage Sense for system-level cleaning.

Do not fill your SSD past 85 to 90 percent. SSDs need some free space to maintain performance and health. If you hit this level, that is your signal to either clean up or upgrade.

Do not rely on defragmenting an SSD. Defragging helps HDDs but it wears out SSDs without real benefit. Windows handles SSD optimization automatically with TRIM.

Do not buy cheap unknown brand SSDs for your main drive. Stick to trusted brands like Samsung, Western Digital, Seagate, Crucial, or Kingston. Your data is worth more than saving $10.

How Much Storage Do You Actually Need in 2026?

This depends on what you do with your PC.

A basic office and browsing PC can get by on 256 GB if you use cloud storage for documents and photos. For most regular users, 512 GB to 1 TB is the comfortable sweet spot. Gamers who install multiple large titles need 2 TB or more since a single modern game can be 100 to 150 GB.

Video editors and content creators working with raw 4K footage need 4 TB or more on fast NVMe storage, plus a large external backup drive.

Conclusion

Getting more storage on your PC comes down to two things: cleaning up what you have and adding what you need. Start by running Storage Sense and Disk Cleanup. Delete old downloads. Uninstall apps you do not use. If you still need more space after that, upgrading your internal SSD is the best long-term investment, followed by adding cloud storage or an external drive for files you do not use daily.

You do not need to be technical to do most of this. Windows makes the basic cleanup tools easy to find. And if you want a hardware upgrade, swapping an SSD is simpler than it looks. The end result is a faster, less cluttered PC that actually has room to breathe.

Frequently Asked Questions

How do I free up storage on Windows 11 quickly?

Go to Settings > System > Storage and click Cleanup recommendations. Windows will show you exactly what it can delete. You can also run Storage Sense manually from the same page. Most users free up 5 to 20 GB in under five minutes this way.

Can I add storage to a laptop without replacing anything?

Yes. If your laptop has a USB port, plug in an external SSD or USB flash drive. If it has a microSD slot, insert a high-capacity microSD card. These add storage without opening the laptop at all. For a more permanent internal upgrade, you would need to check if your laptop has a free M.2 slot or a replaceable drive.

Is cloud storage a good replacement for a physical hard drive?

Cloud storage is a great supplement but not a complete replacement for most users. It depends on having a fast internet connection, costs a monthly fee, and you cannot access files offline unless they are downloaded. Use it for documents, photos, and files you access from multiple devices. Keep your operating system and apps on a local drive.

How much does it cost to upgrade a PC to 1TB of storage?

A 1TB internal SSD costs roughly $50 to $80 in 2026 depending on the brand and type. A 1TB external SSD runs $70 to $100. If you need a professional to install an internal drive, add $30 to $60 for labor at most repair shops. It is one of the most cost-effective upgrades you can make.

Why does my PC say storage is full when I have space?

This can happen for a few reasons. Your C: drive might be full even if another drive has space. Temporary files and system files might have accumulated. The Recycle Bin might be holding gigabytes of deleted files. Check the C: drive specifically, empty the Recycle Bin, and run Disk Cleanup. If the system drive is genuinely full, that is what is causing the problem, not your other drives.
