Since there is no valid reason for wanting to do this, I assume this is for something illegal or offensive, or both. Since you want the file names to be readable I assume this is to destroy someone's data and make it look like an accident or attack.
There are plenty of ways, some so simple (literally 5 minutes' work) that need no programming skill or even a piece of software.
However I cannot support such an operation wilfully without knowing why this procedure is needed. You have to provide a little more detail on this thread, and then and only then can I think about giving you a hint, and that hint will go out over PM. It's not a really big secret, but I wouldn't put my name on such a venture.
Your call.
