Are you really tired of others looking in your most private and confidential files and folders? There`s an easy solution: Encrypt them with ICE Encrypt and the problem is solved.
ICE Encrypt uses powerful encryption algorithms (DES, AES, BlowFish, GOST, etc). In some cases the size of the encryption/de-encryption key is of a million bits, making it absolutely imposible to decypher without the corresponding password. Also, if you use the typical brute force method to get the password, it would take a very long time, as there are millions of combinations.
ICE Encrypt is completely free and also portable, so it needs no installing.
