Why Folder Lock is trusted by experts and government authorities?

We Know What We’re Doing

Folder Lock is in development and improvement since 2002. Yes! We’re older than Facebook and Google. And since then we have not received any reports of any breach of encrypted data caused by the use of our product.

We use our own Products

Yes we really do! That’s how we know which enhancement and bug fixes are vital. We’ve discovered the secret formula; if the product works great for us; it works great for everyone else too. However, your feedback is what keeps us excited and on the track. So never stop suggesting.

Nothing is Swept under the Carpet

We disclose everything in our license agreement, privacy policy, product and website content about the limitations of our products and how we treat your information. Everything is crystal clear; nothing is swept under the carpet.

Endured the Fiercest of Blows

From version 4 to version 10, our company has stood up to a zero debt status and for all these years we have survived and sufficiently handled criticisms, legal actions and other challenges with a clear conscience and a chin up.

No Backdoors; no Loopholes

Folder Lock saves your encrypted files either on your own computer or your own cloud service and not on our server. Furthermore, your passwords are not saved anywhere on your Computer leaving no backdoors [1] [2]. Just be sure to NEVER forget your password, NEVER share your password, NEVER leave your device unattended after decryption and NEVER fall for a hacker’s or a phisher’s trap exposing your password.

Minimal; Feature-Rich; Powerful

Folder Lock is loaded with features that you’ll learn as you continue to use it. It’s both easy to use and feature-rich; thanks to its new uncluttered user-interface. We enjoy handcrafting every bit of it and we hope you fall in love with it. Our inspiration has always been to become a house hold name when it comes to data security. Let us know how we’re doing?

How Secure is 256-bit AES Encryption?

If 10 billion computers are used to attempt to crack data encrypted with 256-bit AES Encryption using ‘brute force’ attack (best known method) then it would take 100 billion years to try all possible keys. And the universe is only 13.7 billion years old[1]. So if you worry about hackers; rest assured they can’t just try every possible password before the heat death of the universe. However, the above scenario is feasible only if you have a good password one that’s not easily breakable by dictionary attacks or guesswork.

[1] More detailed information on the 256-bit AES Encryption is mentioned on this Wikipedia article.

[2] Folder Lock uses military grade 256-bit AES Encryption on all computer files regardless of file format in Desktop Locker, Dropbox Locker, Google Drive Locker and OneDrive Locker folders except for Mobile Locker. In Mobile Locker documents, archives and other formats are encrypted as well except photo, video and audio files. These are mobile only media files. Folder Lock uses another method of data security for these files. Using another method ensures faster content display on mobile devices as there are no fast on-the-fly encryption methods available on mobile phones for large media files).

[3] Whether viruses, hacker tools, trojans, malware, spyware, ransomware, third-party apps, malicious programs or harmful scripts - Since Folder Lock encrypts files on their original location and displays content only in virtual drive and at the same time offers to backup them on the cloud, it offers a reliable method to protect you from all these threats. However, you should still be careful about phishing attacks, keyloggers, clipboard loggers, print screen loggers and many other threats that use other clever methods to breach your privacy. We are planning to introduce anti-keylogger, anti-clipboard logger and anti-print screen logger in future. So wait to be surprised as we roll out updates.

However, since there are privacy matters involved; only authorized US government personals can be furnished with such a disclosure.
