Windows also includes built-in cleanup options.
Protect important folders before cleanup tools remove temporary or old system data.
Step 1. Connect an external drive or choose another safe destination with enough space for personal files on the Windows 10 system drive.
Step 2. Open Qiling Disk Master and choose File Backup. This keeps a copy of important files before you change partitions, boot settings, cleanup options, or Windows installation files.
Step 3. In the tree control, select the files and folders that must be protected. Protect Downloads, Desktop, Documents, Pictures, and any project cache folders that may be important
Step 4. Choose another internal disk, external drive, NAS folder, or network path as the destination. Avoid saving the backup to the partition that will be changed.
Step 5. Review the source and destination, then click Proceed. Wait until the backup completes before continuing with the repair or setup task.
After cleanup, restart the computer and confirm browsers, apps, and Windows Update still work. Review free space in File Explorer.
