Stop User From Shooting Themselves in the Foot

[camball]

Going through the code, I see several spots where a user can overwrite files they don't intend to on their machine.

Devs usually trust that technical users know not to do this, but users of this program can come many backgrounds, some of which are non-technical or have no experience working on a command line. As such, prompting with confirmation messages if a file will be overwritten are a good add for this project.
