A file extension does not always point to the same program. In fact, at times it is impossible to know which file will be opened by which application.

If you are transmitting files over the internet of to another user on a removable drive, security for the data should be your first concern. Password protection is nice to have, but it can be quite a setback if you or the recipient of the file forgets the password. Besides, simple passwords that are easy to remember are also prone to getting hacked easily. Wouldn’t it be nice if you could forego the need of a password altogether and secure the file in a different manner?
