Nowadays it’s very important to keep your sensitive data secure, you could encrypt files or folders with Windows’s built-in encryption or third-party applications, but if we encrypt entire partition or drive, then it’s more easy to manage our files, you can save/copy/cut/paste files on the fly, backup or synchronize files/folders easily.
Comodo Disk Encryption is a truecrypt alternative, it allows you to encrypt local hard drives or partitions, create new virtual drive which is saved in a single file, you can choose between several encrypt algorithms( AES, Serpent, Blowfish, 3DES, Twofish ) and hash algorithms( Whirlpool, SHA1, SHA256, MD5, RIPEMD 160 ).
The encryption progress is automatic, real-time and transparent to you, so you can manage files as if you were working in partitions/drives not encrypted. You can backup and synchronize files with FreeFileSync or other backup and synchronization software. If you stored a virtual drive in a solo file, then you could copy it to a removable media such as USB flash disk or CDs/DVDs, or upload it to an online hard drive such as Dropbox or Live Mesh, etc. Anyone who has no the password can not mount the file as a partition and cannot steal your data.
