I have always taken great precautions to keep my projects self contained. Always organized as folders, with all audio files inside the audio files folder inside the project folder. The very first thing when I start a new project is to save my project organized that way in the right location, then I keep checking in the project folder to make sure everything looks right, and as I record or import audio files in the project (which I never do before saving the project), I keep track of all the files locations by opening a Project File Browser and making it wide so that I can see the entire path to all the audio files. They should always be inside the project as expected.
By doing this I am free to name my files as I want, which is typically rather simple names (Vocals, Guitar, Kick, Snare, etc.).
