rtf files are smaller in size
For new files for notes on a topic, I often
- start it as a rich text format (.rtf) file
- keep editing it for days or weeks for content, not style (finally grows to about 10K in size)
- edit (refine) it with Micro$oft Word (ease of changing font styles, size, colors), ease of paragraph changes
Word saves the file as 15K file (old ".doc" files used to be 40K in size)
- edit it once more using Wordpad (add a space, delete the space) and save the file.
I end up with a 10K file.
I have been doing that process for over a decade both at work and at home.
