If you're using modern applications, you needn't save copies of your documents.
Instead, use version control which is built into many tools.
Copies of files are complicating, confusing, and bewildering for a number of reasons:
you might be editing one copy while another person is working on a different copy
you may not know which is the most current (finalfinal3.doc isn't very convincing)
they are hard to distinguish when doing a file search
There are numerous articles on how to use version control, depending on your application. For Google, try this article: https://www.techrepublic.com/article/version-history-essentials-for-google-docs-sheets-and-slides/
