You should be consistent in the way you name your data files. Consider the following:
- Save every draft with ordinal numbers to mark major changes (1, 2, 3) and decimal numbers to mark minor revisions (1.5)
- Avoid confusing terms like "final" or "revision"
- Keep file names short and relevant: 25 characters is sufficient
- Don’t use special characters in a file name, as they may not be understood by a computer if you move your files
- Use underscores instead of spaces
