ATLOCK v4 Locks Files at OS Level via NTFS ACL Manipulation

ATLOCK's File Guard directly edits NTFS Access Control Lists to lock files at the kernel level, unlike typical apps that only hide or password-protect files. It strips access for all accounts, including administrators, and restores the original ACL on unlock. The tool handles privilege escalation, reversible save/restore, and ACL inheritance to ensure genuine inaccessibility.
