When working on any project, I keep the original version and never overwrite it or change it so I always have a fresh original backup.
Then, as I refine it, add new things, try new things, once I am happy I save it with a number which I increment everytime I make significant changes. e.g
If my original file or template was called "original" I would gradually save the following version
original
original (00)
original (01)
etc..
- this way I can always go back to the original or any other version
- it saves having to remember how to re-create things
- the files get automatically displayed in ascending order (provided that you view them as sorted by name)
- it's good practice to keep incremental versions of files
- it saved my bacon a few times
- I have never reached (99) so far
