What is Deep Scan?
Deep Scan is DiskCleanKit's comprehensive analysis tool. Unlike One Touch Clean, which focuses on obviously safe files, Deep Scan examines your entire system to find all potential space savings.
When to Use Deep Scan
Running low on space and One Touch Clean isn't enough
Before major downloads like new games or video projects
Monthly maintenance for optimal performance
Before system updates to ensure smooth installation
The Three-Panel Interface
Deep Scan uses a three-panel design:
