The build-up of useless data is the main cause of performance degradation on a computer. When your hard drive is full, this can indirectly lead to system overheating and excessive energy use, which affects how long your charge lasts. To tackle this overload and optimise your machine, here are the crucial steps to freeing up space.
The deletion trap: where deleted files are really hidden
Most users instinctively just click “Delete”. However, this only sends the file to the Recycle Bin, where it still takes up part of your hard drive.
- This area is designed as a safety net for recovery, but it quickly turns into a reservoir of useless data.
- The operating system allocates a large amount of space for these items.
- The quickest way to recover space is to locate the Recycle Bin and empty it completely.
The storage control centre: how to read the statistics
For proactive space management, it is essential to use Windows’ built‑in tools to understand how your drive is being used.
- Go to Settings, then select System, and then the Storage tab.
- This summary view gives you a clear overview of the categories using the most gigabytes.
- Once you understand the situation, switch on Storage Sense. This automated service handles regular maintenance by removing unnecessary files without any user action, making sure your drive stays optimised at all times.
Digital debris: getting rid of leftover files
Software and the system generate temporary files for everyday operations, but many of them are left behind after use. The Disk Cleanup tool is designed to remove them.
Key steps for a deep clean:
- Open the Disk Cleanup app and choose the drive you want to clean.
- Then select Clean up system files.
- This lets you remove Windows Update caches, logs and other large files that are usually invisible during a basic clean.
Lightening the load with the cloud: storing photos and videos externally
Media files (holiday photos, video projects, etc.) are the main reason for lack of space on many computers. It is wiser to move them to off‑device storage.
- The OneDrive cloud platform, built into Windows, makes this transfer much easier.
- The “Free up space” option, available via right‑click in File Explorer, allows you to keep only a thumbnail of the file on your computer, while the real file is stored in the cloud.
Outdated software: uninstalling space‑hungry apps
Apps, especially video games, can take up a huge amount of space on your drive. Sorting through the software you no longer use is an excellent way to quickly reclaim space.
- Go to Settings > Apps > Apps & features.
- Use the Size filter to list programmes from largest to smallest.
- Uninstalling the biggest but unused apps is often where you gain the most free space.
Managing multiple profiles: space used by other users
If your machine is used by several people with separate accounts, each of these profiles uses disk space for its own documents and settings.
- To remove unnecessary profiles, go to Settings > Accounts > Family & other users.
- Be careful: this deletion is permanent and irreversible and erases all files linked to that user.
My computer is sluggish: the explanation and the link with battery life
Users often blame a slow PC, with dragging programmes or poor multitasking, on a battery problem. In reality, the real culprit is usually RAM saturation or a processor pushed to its limits. Battery life itself does not slow processes down.
However, a lack of RAM does create an indirect link with your power supply. When the computer no longer has fast memory available, it has to fall back on an area of the hard drive called swap memory to store data temporarily.
This “virtual memory” mechanism forces the hard drive to work much harder and more often than RAM, which results in a significant increase in the device’s overall power consumption.
As a result, energy is drained more quickly and the time your charge lasts drops sharply. If you have already ruled out a RAM issue but your device still runs out of power too quickly, this is a clear sign of a worn‑out battery.
