Settings to Avoid Accidental Deletion on C Drive

Prevention comes from settings—configure once, stay worry-free.

• Whitelist: Add repos, photos, IDs, and VM folders to skip lists.
• Prompts & logs: Enable confirm-before-delete and post-delete reports; save logs to D: or cloud.
• Dry run: Generate a list first, verify safety, then delete for real.
• Permissions: Set winsxs, DriverStore, and other sensitive dirs to read-only and exclude in scripts.
• Automation: Add second confirmations or Y/N prompts to avoid misfires.
• Review whitelists regularly so new projects aren’t missed.

More guardrails = lower fat-finger risk.

Shared home PCs

• Give each person a folder and skip them individually in scripts.
• Require typing “YES” before deletion to stop kids from clicking through.

Log template

Fix fields: time, operator, deleted paths, freed space, exceptions—reuse the template every time.

Parental mode

For parents’ PCs, enforce account control so deleting system paths needs a password—prevents mistakes at the source.

Version control

For long-term directories, consider Git/LFS to save space and prevent accidental deletion—a double win.

Keep an offline backup drive at home; if cleanup goes wrong, restore instead of hunting for recovery tools.

Set key directories to read-only or restrictive permissions to block reckless scripts.
