Wise Disk Cleaner

Clean and Free Up Disk Space

Reclaim Your Storage and Boost Windows Performance

Over time, temporary files, outdated Windows updates, system logs, and uninstalled residues accumulate and clog your computer. This digital clutter takes up valuable storage space and drastically slows down your entire Windows system.

Keep your PC running at peak performance with Wise Disk Cleaner! By regularly scanning and removing these useless files, you can instantly free up valuable disk space, clean up your C drive, and prevent storage bottlenecks from freezing your workflow.

Wipe Digital Traces to Protect Your Privacy

Securely Erase Browsing History and Activity Logs

Every digital action—browsing the web, watching videos, or editing documents—leaves confidential traces cached on your system. Wise Disk Cleaner safeguards your personal information by clearing recently accessed files, Quick Access records, and tracking indicators like browser cache, history, and cookies.

For ultimate security, Wise Disk Cleaner features an advanced Safe Deletion mode. By securely overwriting deleted data, it severely lowers the risk of data recovery software retrieving your sensitive files, keeping your privacy locked away from unauthorized access.

Defragment and Optimize Your Drives

Maximize Speed with Smart HDD Defrag & SSD TRIM Support

Keeping your hard drives and solid-state drives optimized is key to faster boot times and a smoother Windows experience. Wise Disk Cleaner detects your drive architecture and applies targeted optimization to boost overall system responsiveness:

• For HDDs (Hard Disk Drives): It runs an advanced defragmentation engine that consolidates scattered data fragments into contiguous blocks. This shortens file access times and drastically improves disk read/write speeds.
• For SSDs (Solid State Drives): It triggers the native SSD TRIM command. This properly manages unused data blocks and minimizes background write cycles, maximizing write performance and extending your SSD's lifespan.

Schedule Automatic Disk Cleanups

Set-and-Forget Automated PC Maintenance

With the built-in AutoClean feature, you can put your PC maintenance on autopilot. Simply schedule the program to run silently in the background—daily, weekly, monthly, at system logon, or when your PC is idle—and customize exactly which junk items to clear.

Need a quick boost between schedules? Enable the Clean with one-click feature in your settings. This places an optimization widget directly on your desktop, allowing you to instantly free up disk space with a single click without even opening the main app interface.
