The folder was locked. You are sure. Yet someone has seen the files, quoted them, or moved them. This page is not about blame — it is a short, honest list of the only doors a script lock has, and how each one opens from the outside.
A script lock has no alarm and keeps no log, so you will likely never prove which route was used. But the routes are few and well known. Read them as an audit of your own setup: if any one of these was available to the person, the lock was decoration. For each route, this page names the protection that would genuinely have closed it.
Illustration. A script lock guards one doorway and cannot observe — or stop — any other route to the same files.
The most common route needs no skill at all. The intruder right-clicked the locker file, chose Edit, and read your password from the comparison line — or skipped the password entirely and just noted the folder's real renamed name. Total time: under a minute. What would have stopped it: nothing at the script level can. The fix is a different tool — encryption, where there is no readable password stored anywhere on the PC.
The hidden and system attributes are a Windows Explorer courtesy, not a property of the data. Boot the same PC from a Linux USB stick, or take the drive out and attach it to another computer, and the folder appears with its files fully readable — the rename means nothing there, and attributes are ignored. A technician doing data recovery uses this route every day. What would have stopped it: BitLocker or VeraCrypt encryption of the drive or container, which travels with the data itself.
Sometimes no trick is needed. An administrator on the PC can clear the flags with attrib -s -h, rename the folder back, and open it — all with built-in tools doing exactly what they are designed to do. Even a non-admin can often see through the disguise by enabling the display of protected operating system files. What would have stopped it: separate user accounts with NTFS permissions for everyday privacy, and encryption for anything an admin must not read.

▶️ Watch Full VideoYes, in several ordinary ways: reading the password in plain text inside the script file, renaming the folder back and clearing its hidden and system attributes with attrib, or booting another operating system where the disguise means nothing. The files are never encrypted, so none of these routes damages them.
No. A batch script lock keeps no access log, sends no alert and leaves no reliable trace. You generally cannot tell whether the folder was opened, copied or left alone, which is one more reason it must not guard important data.
Encryption. BitLocker on the drive, a VeraCrypt container, or a 7-Zip AES-256 archive make the files themselves unreadable without the key, and that protection holds on other computers and other operating systems. Separate user accounts with NTFS permissions handle the everyday shared-PC case.
