File Encryption Encrypting Security for Windows

Protect and secure your files
File Encryption is a great application which allows users to protect their files. Those are files that are resting on our hard drives, usb drives or any other type of digital media storage.

Those are files that are usually not meant to be sent through network, they are stored locally, being encrypted and temporarily decrypted while being used and than encrypted again after we finished using them.

Encrypting stored files prevents others from reading, copying, or deleting encrypted files. Most often, those encrypted files can be seen in a file listing (such as in file explorer), but they can not be accessed for reading by unauthorized persons. Some file encryption programs require you to decrypt the file before it is used, or read, and this requires you to enter a password, pass phrase, or pin code do decrypt file for viewing.

These programs do not rely on the file system such as FAT, NTFS, etc. Others, like Windows EFS do rely on the file system. Windows EFS offers encryption in a transparent state – the file will be automatically or transparently encrypted or decrypted on the fly. That is possible because Windows EFS is built into the operating system – it uses your user and password when you log in into Windows. Such decryption is fast, almost real time, which means there is no noticeable performance overhead when accessing and reading files on disk.

A thing to note is, file encryption will not prevent the files from being deleted from hard drive, or usb drive, so it is wise to have a backup copy of those files. Also, most file encryption programs will not automatically re-encrypt files after use, and those files should be re-encrypted after use.
