Folder Lock Review: Is It Worth It for Windows Encryption?

Folder Lock is a paid Windows utility from NewSoftwares that wraps encrypted lockers, folder hiding, cloud backup, password wallets, and file shredding into one installer. We installed the current build on Windows 11, spent a full week moving real files in and out, and compared its quirks against BitLocker and Bitwarden’s free tier. This review covers what Folder Lock is actually good at, where it feels dated, and whether the one-time $39.95 license beats simpler free options for everyday Windows users in 2026.

Using these methods on devices or accounts you don’t own may violate applicable laws and platform terms.

#What Folder Lock Does and Who Should Care

Folder Lock is a Windows-only file-security suite developed by NewSoftwares. The official Folder Lock product page describes it as a combined tool for password protection, encryption, secure backup, password wallets, and secure deletion. Put another way: the app tries to cover everything a casual Windows user might otherwise stitch together from BitLocker, 7-Zip, Bitwarden, and Eraser.

The target user is not a security engineer. It’s a parent, small-business owner, or freelancer on one Windows laptop. We tested on a Dell XPS 13 running Windows 11 Pro 23H2.

Folder Lock is not the right fit if you work across Windows and macOS, if you need Linux support, or if your threat model assumes a motivated attacker with physical disk access to the drive. For whole-disk protection on a stolen laptop, Microsoft’s own BitLocker documentation covers a more appropriate model that encrypts the entire volume before Windows even boots. Folder Lock protects specific files and folders while the rest of the drive stays readable, which is a different and complementary security posture, not a replacement for full-disk encryption. In practice, the two tools compose well when you run them together on the same machine. Skip BitLocker at your own risk on any laptop that leaves the house.

#How Does Folder Lock Encrypt Your Files?

Folder Lock has two different protection modes, and people mix them up constantly. The Lock Folders mode hides and password-gates files using a proprietary driver, but the underlying data stays on disk in its original form. The Encrypt Files mode creates a locker, an encrypted container that behaves like a virtual drive, and encrypts contents with AES-256. Only the second mode gives you actual cryptographic protection.

#AES-256 Lockers

Lockers are the feature you actually paid for. According to NIST’s AES specification (FIPS 197), AES with a 256-bit key is the standard the US government approves for TOP SECRET data, and the same cipher powers BitLocker, VeraCrypt, and Bitwarden’s vault. Folder Lock’s locker is a single .flk file that grows as you add content. When the locker is closed, the file is just ciphertext; when you unlock it with the right password, a virtual drive letter appears in File Explorer and you drag files in or out.

When we tried this on a 2 GB locker with 400 mixed PDFs, images, and Office documents, open-and-close operations felt indistinguishable from a regular folder. The locker file itself showed no readable strings when opened with a hex editor, which is the expected behavior for a correctly encrypted container.

#Lock Folders (Hide Only)

The Lock Folders mode is weaker than most users assume. It hides files from File Explorer and blocks access through normal applications, but it doesn’t encrypt the bytes on disk. NewSoftwares’ own FAQ confirms that the locking feature relies on a kernel driver and that booting into Safe Mode or mounting the disk from another operating system may expose the locked folders.

We verified this behavior ourselves. After locking a work-documents folder on our Windows 11 test install, we rebooted the same machine from a standard Ubuntu 22.04 live USB and the supposedly-hidden files were immediately visible in the mount. That’s the expected result given the architecture, but it surprises users who treat “Lock Folders” as equivalent to encryption. Use Lock Folders for casual privacy against a family member or coworker who sits down at your unlocked desktop. Use Encrypt Files (the locker mode covered in the previous section) for anything you wouldn’t want a forensic recovery service or a determined technical attacker to see, because only that mode applies real AES-256 cryptography to the bytes on disk.

#Secure Backup: Pricing and What It Protects

Secure Backup is an add-on cloud service that syncs encrypted lockers to NewSoftwares’ own cloud, billed separately from the desktop license. You create an account, choose a storage tier, and the app uploads new or modified lockers in the background.

#Cloud Storage Pricing

The Folder Lock cloud pricing page lists these monthly tiers at the time of testing:

• 10 GB: $5 per month
• 20 GB: $10 per month
• 50 GB: $20 per month
• 100 GB: $30 per month
• 200 GB: $60 per month
• 500 GB: $100 per month
• 1 TB: $200 per month
• 2 TB: $400 per month

That is dramatically more expensive than general-purpose cloud storage. Google One charges $9.99 per month for 2 TB. Apple iCloud+ charges the same. Folder Lock’s premium is for zero-knowledge encryption of the data before it leaves your machine, so NewSoftwares can’t read your files on their servers. For mainstream users, a standard cloud plan plus a separate encrypted locker inside it usually costs less. For a comparison with a general-purpose option, see our Degoo cloud storage review.

#What Backup Actually Protects

Backup protects against drive failure and ransomware, not against a lost password. If you forget the locker password, nobody at NewSoftwares can recover it. The encryption key is derived from your password, so the support team never holds it. This is the correct security posture, but it’s also a footgun for people who reuse the backup as a password reset path. It doesn’t work that way.

#Sync and Restore Limits

Restore is locker-based, not file-based. You download the whole container, not individual files, so small archives restore in minutes while a 500 GB archive over a home connection may run overnight.

#Folder Lock Security: The Good, the Less Good, and the Limits

Security has two layers here: the cipher and the implementation. The cipher is industry standard. The implementation is what people should examine.

#The Good

AES-256 in a locker-style container is a known, well-studied pattern. VeraCrypt uses the same approach and has been audited publicly. The NIST AES standard (FIPS 197) covers the math; there is no proprietary twist to worry about in the cipher itself.

Password Wallets add a second encrypted vault for credit-card numbers, Social Security numbers, and login details, with nothing in plaintext on disk. For a dedicated password manager with open-source code and true cross-device sync, our Bitwarden review covers that route. For a combined file-and-wallet tool on one Windows machine, Folder Lock is the simpler consolidated choice.

#The Less Good

NewSoftwares does not publish third-party security audits the way Bitwarden does, and no public penetration-testing report appears on the Folder Lock site. Lock Folders relies on a kernel driver that has historically had minor bypass reports in security forums. This is why we keep recommending you use Encrypt Files for anything that actually matters, and treat Lock Folders purely as a hiding layer for casual privacy. The cryptography itself is fine, but the implementation is a black box that you have to decide whether to trust based on your threat model. If you’re encrypting something a motivated attacker would be willing to pay a specialist to recover, this is a bigger concern than for a user hiding tax PDFs from family members.

The “hack attempt” screen logs incorrect password attempts and can trigger shutdowns. Impressive-looking, but it only runs while Folder Lock is running; a live USB boot bypasses it entirely. Treat it as a deterrent for casual snooping, not a hard security control that stops a motivated attacker with physical access to the machine.

#When Not to Use Folder Lock

Skip Folder Lock if any of these apply: you work across macOS or Linux; you need full-disk encryption (use BitLocker or FileVault); your files must stay encrypted inside a regulated compliance boundary (HIPAA, PCI-DSS) that requires audit documentation Folder Lock can’t supply; you already run VeraCrypt and a password manager, and don’t need the consolidation.

#Extras: Which Ones Earn Their Keep

After a week of testing, three extras stood out as actually useful and two felt like filler.

#Useful: Shred Files

The Shred Files tool is the underrated feature. Deleting a file from Windows, even with Shift+Delete, only removes the filesystem pointer; the bytes stay on disk until overwritten. Microsoft’s own SDelete documentation confirms that secure deletion requires explicit overwrite passes. Folder Lock’s shredder handles this in a friendlier interface than SDelete’s command line. You can shred free space on a drive too, which overwrites all previously deleted but unrecovered data.

In our testing, a 1 GB free-space shred on a 500 GB SSD took several minutes. For HDDs the process is much slower, which is normal.

#Useful: Portable Lockers on USB

Folder Lock can convert a locker into a self-executing file on a USB drive. The recipient does not need Folder Lock installed; they run the executable, enter the password, and the locker mounts. For sending encrypted files to a client who does not have any security software, this is the easiest workflow we tested. A similar goal can be achieved with VeraCrypt portable mode, but Folder Lock’s wizard is less intimidating for non-technical recipients.

#Useful: Email Attachment Encryption

Right-click, encrypt, and send. The email client receives a password-protected zip or locker and you share the password out-of-band. Gmail and Outlook both happily forward the attachment because it looks like a normal archive.

#Skippable: Stealth Mode

Stealth Mode hides the Folder Lock icon, system tray entry, and Start-menu shortcut, then makes the app reachable only through a configurable hotkey. In practice it adds friction every time you want to use the app without giving you real security benefit, because a determined searcher will find the install directory under Program Files, spot the running process in Task Manager, or see the driver load during boot. The hotkey itself becomes a secret to remember. We tried Stealth Mode for two full days of normal use, and the end result was that we simply forgot the combination twice and had to reinstall. Leave it off.

#Skippable: Clean History

The Clean History tool wipes recent-document lists, MRU entries, and clipboard data. Windows itself and your browser already expose most of these controls. We did not find a scenario where Clean History protected something the OS native tools could not.

#Folder Lock vs Free Alternatives (BitLocker, VeraCrypt, Bitwarden)

This is where Folder Lock’s value proposition gets harder. Each of its pillars has a strong free or cheaper competitor:

• Encryption: VeraCrypt is free, open-source, and audited. It handles lockers and full-disk encryption on Windows, macOS, and Linux.
• Full-disk protection: BitLocker ships with Windows 11 Pro at no extra cost. The BitLocker overview recommends it for any laptop that leaves your home.
• Password vault: Bitwarden’s free plan includes unlimited passwords across devices. Our Bitwarden review covers the setup in detail.
• Secure deletion: Microsoft’s SDelete (free) or Eraser (open-source) both shred files without cost.
• Cloud backup: Tresorit, Proton Drive, Sync.com, or a standard provider plus encrypted lockers all beat Folder Lock’s per-GB price.

The pitch for Folder Lock is not “best in any one category.” It’s “one installer, one price, everything handled.” That pitch works if you value not managing five tools over saving money. It doesn’t work if you’re already comfortable with a password manager and basic Windows security. For users who also need to recover an encrypted file they can’t open, techniques for removing a forgotten PDF password or unlocking a password-protected PowerPoint are separate workflows entirely, not something Folder Lock addresses.

#Drawbacks You Should Know Before Buying

A week of daily use surfaced these friction points.

Windows-only. No macOS client, no Linux build, no Android app, no iOS app. If you work across a MacBook and a Windows PC the way many freelancers do, your lockers can’t follow you between machines unless you keep the portable USB version plugged in, which defeats the “set it and forget it” appeal. The mobile Folder Lock apps that appear in the App Store and Google Play are separate products from NewSoftwares, built for hiding photos and notes on a phone, and they don’t share lockers with the desktop version. If cross-platform matters, VeraCrypt or a combination of BitLocker plus 7-Zip encrypted archives plus a password manager will map better to your workflow.

UI feels dated. Cosmetic, not a security issue, but icons and fonts still read like late-Windows-7 era.

Cloud pricing is high. The cloud storage tiers cost several times the rate of general-purpose cloud plans. You pay the premium for zero-knowledge encryption, but most users can recreate that with a standard cloud provider and a VeraCrypt container for less money.

No open-source audit. Closed source, no published pen-test, unlike Bitwarden or VeraCrypt.

Password recovery is unforgiving. Lose it, lose the data. Write the master down before encrypting anything important.

Credit card required for backup trial. The Secure Backup free trial requires a card on file. If you cancel within 30 days you are not charged, but the pattern irritates people who dislike gating trials behind payment details.

#Is Folder Lock Worth the $39.95 License?

For a Windows-only user who wants one tool to hide folders, encrypt files, wallet away passwords, shred old drafts, and optionally back up encrypted lockers to the cloud, yes, $39.95 as a one-time license is reasonable. In our testing, the consolidation was real: one install, one update, one support channel, one password to remember.

For anyone already using BitLocker plus Bitwarden plus a standard cloud provider, Folder Lock duplicates features you already own for free. For macOS and Linux users, Folder Lock is simply not an option and you should stop reading marketing pages that suggest otherwise. For a related use case like tightening household device permissions, our access control security guide and best parental control router roundup cover adjacent ground Folder Lock does not touch at all.

#Bottom Line

If you are a Windows-only user on a single laptop and the idea of one installer covering encryption, shredding, password wallets, and cloud backup appeals to you more than stitching together VeraCrypt, Bitwarden, Eraser, and Tresorit, buy Folder Lock for $39.95 and skip the Secure Backup add-on. Use Encrypt Files (lockers), not Lock Folders, for anything sensitive, and write the master password on paper before you start. Everyone else: use BitLocker, Bitwarden, and a standard cloud plan instead; Folder Lock does not add enough over the free Windows stack to justify the license.
