I’m working by myself on a project. I’d like an easy to use, free, version control system that integrates with IntelliJ IDEA nicely. I’d prefer if the whole repository was isolated to a single file, or folder, so that I could back it up on a USB stick easily and transfer it to another computer.

Take a look at Git. The whole repository is in the
.gitdirectory under your project root (by default) and I believe IntelliJ IDEA just integrated Git functionality recently.Assuming you are going with the default (having the
.gitdirectory in the project root), then you can just copy your project to a USB stick and you have your project and repository to go.
