DiskCryptor

DiskCryptor is a free and open source program for partition encryption in Microsoft Windows. It is a great choice for people who need to protect their sensitive data from unauthorized access. DiskCryptor uses strong encryption algorithms to ensure that your data is safe even if your computer or disk is stolen.

DiskCryptor is very easy to use. Just select the disk or partition you want to encrypt and enter the password. DiskCryptor will then encrypt the selected disk or partition and save the password to a file. You will need the password to decrypt the disk or partition if you ever need it.

DiskCryptor is compatible with most partitions and Windows operating systems. It is also compatible with TrueCrypt, which means you can use DiskCryptor to decrypt partitions that have been encrypted by TrueCrypt.
