You don't really need to "secure" a folder to send it over the network as the wireless encryption takes care of it for you. You can use a third party folder encryption app or compress the folder and give it a password if you really want to have overkill. If you're just on a Home network, as in using it in your home, then all you need to do is set the wireless encryption to WPA-2 (it's the highest non commercial encryption) and everything you send to the other computers is encrypted. Depending on the uniqueness of the password, (length of password, how many numbers, random letters, uppercase letters, etc.) it could take years to decrypt even with a high end "cracker".
The Password folder app enables users to keep their information secure by acting as a vault so one's data can be totally secure. All information fully secure and encrypted so it is protected by malware, hackers, and thieves.
