The Windows operating system does not ship with a program that can be used to password protect files easily. There are on the other hand several reasons why someone would want to password protect files. This can be to protect children by preventing their access to certain applications or files, protecting files in case they get lost and basically any kind of files that should not be opened by unauthorized users.
Androsa FileProtector is a software to password protect files on internal and external hard drives connected to the PC system. It can be downloaded as a portable version or one that has to be installed on the computer system. Three different encryption algorithms can be selected to password protect the files including 256 bit AES encryption which I'd recommend you use when you make use of the program.
Using the software program is actually pretty straightforward. Files can be added by using the built-in file browser. The files that have been added can then be password protected in the next step. The FileProtector will then encrypt the selected files and change their file extension to .afp. That file extension is automatically assigned to the software if it is installed on the computer system so that you can open the files with a double-click and always know if a file is encrypted. Portable users will have to assign it or select the program from a list if they want to decrypt protected files.
The software can also delete files securely by overwriting them a number of times. This is an important step as the original files will be deleted after the encrypted copy has been created. Androsa FileProtector will display a password prompt if the file is executed on the computer system.
