# How to Free Up Space on Your Windows PC Efficiently A step-by-step guide to identify and remove unnecessary files on Windows. - **Source:** [Engadget - Technology News & Expert Reviews](https://brifing.si/source/16dd2da6-3eea-4d1e-b34f-45e846cdf037) - **Published:** 2026-09-04 - **Topic:** [Career Growth](https://brifing.si/c/growth) - **Original article:** - **On Brifing:** https://brifing.si/s/2f3c90ad-1bf8-459a-b0ca-afdf66b2269e ## Start with Windows' built-in storage tool Press Win + I to open Settings, then navigate to System > Storage. This tool provides a breakdown of disk usage by category, such as apps, temporary files, and system data. Clicking each category takes you directly to the relevant management options. For example, 'Installed apps' lets you sort by size and uninstall unused programs. Temporary files can be cleaned up with a single click, but be cautious with Downloads and Recycle Bin to avoid losing important files. ## Manage installed applications Large applications, especially games, can consume significant space. In the Installed apps section, sort by size to identify the biggest offenders. Some apps offer a 'Move' option if you have multiple drives. Uninstalling unused applications can free up gigabytes quickly. Remember to check both Program Files and Program Files (x86) directories, as they house most installed software. Avoid deleting files directly; always use the uninstall option to prevent system issues. ## Clean up temporary and system files Temporary files, including thumbnails and update leftovers, can be safely deleted. Click 'Cleanup System Files' to reveal additional categories. System Restore points can also take up space; reducing their number or deleting them entirely can reclaim storage. Disabling hibernation via Command Prompt (powercfg /hibernate off) removes the hiberfil.sys file, which can be several gigabytes. Always review files in the Recycle Bin before emptying it permanently. ## Use third-party tools for deeper analysis TreeSize Free is a powerful tool to visualize folder sizes. Run it as an administrator and scan your C: drive to identify large folders like Program Files or AppData. Expanding directories helps pinpoint specific space hogs. Another tool, dupeGuru, finds duplicate files that TreeSize might miss. These tools provide a granular view of storage usage, making it easier to decide what to delete or move to another drive. ## Optimize personal files and media Check the Users folder for large personal files like videos, photos, and downloads. Move rarely accessed files to an external drive or cloud storage. Services like Google Photos or YouTube can offload media while keeping it accessible. Configure OneDrive to keep only recent files locally. Clearing browser caches and app downloads in AppData can also free up space. Always ensure important files are backed up before deletion. ## Consider external storage solutions If internal storage is consistently low, investing in an external SSD or HDD is practical. SSDs offer faster speeds but are more expensive, while HDDs provide cost-effective bulk storage. Even USB flash drives can serve as temporary solutions. External drives are ideal for storing large files like media libraries or backups, reducing the need to delete important data. Regularly transferring files to external storage can maintain optimal system performance. ## Automate cleanup with Storage Sense Enable Storage Sense in Settings > System > Storage to automate junk file removal. This feature periodically cleans temporary files, Recycle Bin, and Downloads folder based on your preferences. You can customize the frequency and specify which files to delete. Storage Sense helps maintain free space without manual intervention, ensuring your PC runs smoothly over time. Combine this with periodic manual checks for best results. ## Best practices for ongoing storage management Regularly audit your storage to prevent clutter from accumulating. Uninstall unused apps, clear caches, and move large files to external drives. Use cloud services for backups and offloading media. Tools like TreeSize and dupeGuru simplify identifying space hogs. Automate cleanup with Storage Sense to reduce manual effort. By adopting these habits, you can maintain ample free space and avoid performance issues on your Windows PC. ## Sources covering this story - https://www.engadget.com/2247848/how-to-see-whats-taking-up-space-windows/ — --- _Summary written by Brifing from the original reporting.
