I still have a Risc OS machine. I just tried writing a few lines of text and then looked at the resulting file in a plain-text editor. There are a few bytes of control codes:
But the rest of it is just plain text, presented as-is. Total size: 239 bytes.
Obviously adding more fonts, bold, underline etc will increase the size, but not by much! And until you start embedding images and other "fancy" things there's nothing that will bloat the file. It does make you wonder what the modern word processing tools are doing...
I totally agree with you! It is not a matter of writing with real paper or using bludgeons like someone is sarcastically saying.
It is deliberate waste of valuable disk storage to encourage customers to buy more and more demanding hardware which fosters more and more demanding software which fosters more and more demanding hardware... and so on, ad infinitum.
I've created a text only
Pages document and opened it with the .zip trick.
Well, of an overall size of 740 KiB there is a Preview Jpeg 110KiB large, along with 6 PresetImageFillsXXX.jpg, each weighing roughly 90KiB, so that of 740 KiB, 650 KiB are wasted for (useless?) JPG.
