We often think our PC becomes slow because of big files, heavy programs, or updates. But surprisingly, one of the most common reasons behind slow apps, crashing games, and random errors is an invisible folder that quietly collects junk over time — the AppData folder.
If you’ve ever wondered why an app refuses to open or why storage keeps shrinking even though you didn’t download anything new, AppData is often the hidden culprit.
Today, let’s walk through this process in a gentle, step-by-step way so you not only delete the right files but also understand what you’re doing and why it is safe.
Understanding the AppData Folder
Before we jump into the steps, it’s important to understand what AppData really is.
Every application installed on your PC needs a private space to store:
- cache
- temporary files
- logs
- saved settings
- leftover data from updates
Windows quietly stores all of this inside AppData, and because it’s hidden by default, we tend to forget it even exists. Over time, these files pile up — especially if you’ve installed and uninstalled many apps. That buildup becomes clutter, and clutter always slows things down.
So clearing AppData is a bit like cleaning the room you never open. Once cleaned, everything else starts functioning more smoothly.
Opening the AppData Folder
Before we start deleting anything, let’s first reach the correct location. Here too, Windows makes it simple, but it helps to know what you’re looking at.
🌱 Intro to This Step
The AppData folder has three subfolders — Local, LocalLow, and Roaming. Different apps use them for different reasons. We won’t delete everything, only the safe-to-remove parts.
Steps to Open AppData
- Press Windows + R on your keyboard.
- A small Run window will appear.
- Type the following command exactly:
%appdata%
- Click OK.
This will open the Roaming folder by default, but don’t worry — we need to move one step back.
Navigating to the Complete AppData Directory
When the Roaming folder opens, look at the top navigation path and click AppData to go one directory back. Now you will see three folders:
- Local
- LocalLow
- Roaming
Each contains different types of application data, but the safest files to clear are usually inside Local → Temp.
Let’s move there next.
Safely Clearing Temporary Files
Whenever apps run, they create temporary files — things they need only for a moment. But they rarely clean up after themselves. Over weeks and months, this folder can grow into gigabytes of useless data.
🌱 Why This Step Helps
Deleting temp files can fix:
- apps not launching
- games crashing
- programs taking too long to load
- storage running out mysteriously
- leftover junk from uninstalled apps
These files are safe to remove because Windows recreates them automatically when needed.
Steps to Clear Temp Files
- Open the Local folder.
- Find the Temp folder.
- Open it — you will see dozens or hundreds of files.
- Press Ctrl + A to select everything.
- Press Delete.
Some files may refuse to delete because they are currently being used by Windows or another app. Simply skip those.
This single step often makes apps load faster and removes unnecessary clutter instantly.
What About Roaming and LocalLow?
This is a common question.
While both folders contain important app settings, only leftover folders from uninstalled apps should be removed. If a folder clearly belongs to an app that no longer exists on your PC, you can delete that folder safely.
But do not delete folders randomly — many apps rely on Roaming for saved data.
So the safest cleanup routine is:
- Delete Temp folder content
- Remove leftover folders from uninstalled apps only
Nothing else.
Why Clearing AppData Improves Performance
Once the AppData folder gets heavy, apps begin to behave strangely. Some refuse to open, others crash midway, and certain programs take forever to launch because they’re trying to read from outdated or corrupted cache files.
Clearing the junk brings your system back to a fresh state — not a factory reset, but a gentle reset for the apps. This often feels like giving your PC a small breath of fresh air, especially if it hasn’t been cleaned in months.

Final Thoughts
Cleaning the AppData folder is one of those tiny habits that keeps your Windows PC running smoothly. It doesn’t take more than a minute once you know where to look, yet it solves so many problems — slow apps, unexpected crashes, and storage warnings.
Think of it as clearing the dust that quietly settles behind the furniture. You don’t see it every day, but when you clean it, the whole room feels lighter.
⚠ Disclaimer
Deleting files inside AppData is generally safe only when you remove temporary files and leftover folders from uninstalled apps. Do not delete system folders or files belonging to active programs. Always close important applications before cleaning AppData.
