The problem would this type of program is in things going wrong such as a faulty usb drive or when you upgrade your operating system hen will the program still work. It would be less worry if you have access to backup ed data if something does go wrong but if your a traveler and want data locked up without exposing a backup copy then there could be a problem.

Zipping up data with a password is still my preference choice.

Programm is old (yes!) VMWare portable made today on vm32 xp runs smoothly on win 64 bit systems.
Regdata and setup can be stored. Password available tru Sticky PW cloud-on. The few folders that need hiding/encrypting are manageble. Tested with recovery SW - don't delete and/or rename a file before protecting it. It can be found then again who's looking for it CSI FBI? They can force you to give them the pass or go to jail for a long time.

Drawback vm from usb - rightclick in explorer doesn't work, do I care, Neh! A gem used in combination with Sticky Password for the files you want to keep hidden...

A keeper for sure! (sorry I don't handout vm's to anyone...)

This places a hidden file named "+" in your installed folder in your hard drive.
That file cannot be accessed.
The software places the files:
Unins000.dat and Unins000.exe
in a separate folder named "Uninstall Password Protect USB"
As with any locking or encryption software, you need to prepare for the contingency of this software being damaged somehow; after the 1 day (in this case Activation by File) expiry has passed. In that scenario, you have to buy the software or else all your locked files and folders cannot be accessed.
So if you like this software, buy it for use.
If you do not intend to buy it, then DON'T use it. Uninstall the software or better still, do not even install it in the first place. During the uninstall process, a pop up notice appears in the PC saying: " ncfpsys.dll will no longer auto start "
Even after a Revo Uninstall, use a thing like Regseeker (you must know what you are doing) to really clean out all traces of this from your PC.

Freeware alternatives are available. In any case, nowadays if you buy certain brands of USB drives such as for example Sony or Imation, they all come bundled with proprietary USB encryption software given away free with the hardware USB that you bought. So this passwordprotectUSB software is really unnecessary.

Downed and installed as it is. To my taste and can be used anywhere even your hard drive (fixed) or usb. But big folder can cause bugs. Thanks.

$40 - Really ... when there are so many free alternatives such as
FREE SafeHouse Explorer Encryption
http://www.safehousesoftware.com/

I've used this for a few years and it works as advertized on their website.

"Is a FREE super-strong 256-bit encryption software for any hard drive or USB Flash memory stick. Total privacy with a familiar Windows Explorer-like interface.
PASSWORD PROTECT - MAKE FILES INVISIBLE

Full version is 100% FREE to everyone.
Complete stand-alone privacy solution.
Can run directly from USB memory sticks.
Can create self-extracting encrypted vaults.
Easy to use, nothing to learn."

Doesn't support files with more than 4GB! - very, very, very slow with huge directories !

To the developer: If you boot into a live CD/DVD/USB like Linux Puppy or Mint and mount the protected drive, will the drive mount and will the drive still be protected from access?

This software does not work properly on a USB-stick.
It is not possible to protect a folder on a stick, travel and try to open the folder on another computer.

I installed the software of today and protected a folder on a stick.
After that, I plugged the stick in another PC with another Windows.
Windows couldn't open the folder; also did not give a pop-up for a password.

I have to install a trial, version 3.2.0.1, downloaded today from the site.
Now I could open the protected folder.
Only: no more then 3 folders are supported and a max of 50Mb.

"This program can protect your folders, but (as far as I know) can’t hide them. But Protected Folder by IObit can."

There is no real way to hide data written to whatever storage media -- you might not be able to read it if it's encrypted, but the fact that it's there is easy to determine. Software that *hides* folders generally tells Windows not to see them. Look at the drive outside of that copy of Windows with that software installed, & any hidden folders are as visible as ever. That's not to say hiding a folder may or may not be useful to you personally -- only that it can be easily seen.

The reason for this post however is to point out what I think is the current thinking when/if you really do need to hide the existence of a file or files, folders etc... Generally they recommend one or more layers of nesting -- putting an encrypted VHD inside another encrypted VHD. The idea is that if you're forced to reveal the key to the encrypted VHD, hopefully it'll stop there, & the 2nd encrypted VHD will go unnoticed. Obviously that would be dependent on there being a whole lot of files in that top level VHD, e.g. a copy of Windows.

"You can only “unlock” your folder on an USB drive with another computer, if you have this small encryption software installed."

Back in 2010 [I *think*] GOTD had an app called USB Stick Encryption by Gilisoft -- http://gilisoft.com/how-usb-stick-encryption.htm

It created a single file [agent.exe] on the USB stick, that when double clicked/run, would ask for a password. If the correct password was entered, it would install its driver [if not already installed], & open what appears as another USB drive, similar to the way you'd access an encrypted VHD e.g. from Truecrypt.

To eject/dismount the USB stick you stop the agent app by right clicking its icon in the Notification area or Taskbar, then proceed normally right clicking the USB icon to safely remove.

The closest I have seen in free-ware is Veracrypt, one of I think a few forks or continuations really of the Truecrypt project. It has a method for putting a Veracrypt encrypted VHD on on a USB stick along with the Veracrypt files to access or mount it. http://sourceforge.net/projects/veracrypt/

I think there are basically 2 main ways to manage encryption -- either encrypt/decrypt files when/as needed, e.g. create an encrypted 7-zip archive, & later extract those files, or do the encryption/decryption on the fly, e.g. access the encrypted files in a Veracrypt container. The latter generally means a driver is needed [must be installed], which is not always possible in every situation, & requires that the software on a USB stick for example, must be capable of installing that driver(s), e.g. the Gilisoft app & Veracrypt.

This program can protect your folders, but (as far as I know) can't hide them. But Protected Folder by IObit can. It gives better security. TreeSize (as mentioned by Jahid) could not find a folder protected by IObit.

I think this type of folder locker programs are helpful for casual usage. For very confidential documents it will be risky if you rely on these progrmas.
When You'll lock any folder by password it doesn't mean that the content inside that so called 'protected folder' won't be accessible. Off course they can be accessed until unless those files are individually encrypted. Yes, it is possible. I wrote many a times earlier about this.

1st Method :

There is a program named WinUtilities Undelete basically a program for retrieving deleted data but it can show folder and files locked by any Folder lock program without using any password . It has a explorer based GUI. Normally after being locked/hidden the folder become 'System Folder' which can not be accessed from windows Explorer. But after analyzing a drive with 'WinUtilities Undelete' you can easily get inside that folder and copy all/selected contents to another location and get the access.

2nd Method :

Another popular program TreeSize Free can be used to acess files inside the 'protected folder' . The program is mainly disk analyzer which can show you which files take up the most space on your hard drive. So when you analyze a disk it will show all the folders and the contents inside those folder. When you double click on a folder protected by any Folder Locker / Hider the access will be denied but if you double click on contents within those folders they will be opened with their associated programs.

Sensitive data has to be protected somehow. If it via encryption or password protection may be the user's decision. I prefere password protection, and will grab today's offer for my travel companion (Lenovot420s) The data, I carry around, is my responsibility, and I have been very aware about that matter, since a company computer was stolen. Sorry, to share a bad experience right from the early morning - here in Denmark, anyway. Try and watch this video about setting passwords for your external devices.

Thanks to Password Protect Software and GAOTD for the opportunity to use tis software. Have a great and sunny weekend.

Installed and registered without problems on a Win 8.1.3 Pro 64 bit system. A clean install.

A company with a Canadian postal address.

After a test a simple review...
http://i.imgur.com/WsmQ5SK.png

The software is from 2005. Nothing bad about this.
"Locking" a folder is a misleading term. It does "lock" a folder by encrypting this with an unknown method. It is a most simple file encryptor, which can take a long time (hours!) with big folders on an USB drive.
http://i.imgur.com/axT7fsW.png

The software does nothing else than every encryption tool, free or paid.

You can only "unlock" your folder on an USB drive with another computer, if you have this small encryption software installed. The only marketing gag is to call an encrypted file/folder a "locked" file/folder or "password protected".

Does anybody really pays for this???
Uninstalled via reboot
Have a nice weekend!

download and ran as stated in the read me file. tried to lock folder and just kept getting error contact support..deleted
