What Are File and Folder Permissions

Permissions define which users or groups can read, write, or modify files and folders. Windows enforces these rules through Access Control Lists, so every item checks who tries to open or change it. When you understand these rules, you avoid accidental data loss and unwanted access.

Why Permission Changes Matter

Correct permissions prevent unauthorized users from opening, editing, or deleting your files. They also help applications access only the folders they need, which improves stability and reduces crashes. When something breaks, you can restore order by resetting everything to the original state.
