Secure Folder is a newly developed lightweight app that allows users to quickly secure important files. There are two modes – Low Security and High Security. The low security mode allows users to encrypt the files so that they are not accessible over the network. While the high security mode can password protect the app so that no one is able to access the files(including other computer account holders)
Update: Secure Folder for Windows has been discontinued. However, you can check out Cryptor and Secret Data Manager to protect your files.
You need to keep a strong password, otherwise the OK button will not be highlighted. Once you have selected a strong password, hit Add and add as many files as you can. The files are first encrypted and then added.
It is a great little app but the only major turn off that is keeping me away is the 5MB file limit. Yes, you can’t add files that are larger than 5MB. So the only usage of this app could be to secure PDF and Word documents that are under 5MB.
It works on Windows XP, Windows Vista, and Windows 7. Enjoy!
