Folder Latch

Folder Latch is an efficient and reliable software solution that can come in handy to those of you worried about the safety of their files and folders.
The program is fairly easy to use, you simply choose the operation you wish to perform – either lock or unlock a folder - then select the directory you wish to protect and type in the password as well as its verification.
You can opt to enter a password hint, if you are prone to forgetting it or if it is particularly difficult to remember. After that, you choose the protection mode and press "Protect" to encrypt it.
Additionally, it offers you a recommended "Verify Un-protection" option that checks whether you will later be able to unlock your folder or not, for safety reasons.
The program warns you that if you try to password-protect folders larger than 4 GB, you run the risk of losing them, as it does not guarantee their safe recovery. You can, however, split the large-size directory into several smaller ones.
The program offers two modes of protection: "Real" and "Test/Media". The "Real" mode simply encrypts the folder to a SBX format that can only be unlocked using Folder Latch. The "Test/Media" mode creates a copy of the folder and encodes it, allowing you to keep the unencrypted version and transfer the locked file to a USB driver or send it via email to a friend.
In order to unencrypt a directory, you need to specify the driver on which it can be found and the program will automatically detect all SBX files in that location. Within seconds, the selected folder is unlocked and you can once again access the files inside.
Folder Latch is a user-friendly utility despite the numerous warnings it displays, as it provides you with an additional security measure, which is particularly important when sensitive documents are involved.
