blank cells not blank

[cbrf23]

I have a file, which somehow is 8.59mb in size, and has almost nothing in it.

I have data in range A1:F29.

I deleted rows 30:63556 (last row in worksheet) and also deleted columns G:IV (last column).

No reduction in filesize.

I then copied the data (range A1:F29) to a new workbook. Filesize then goes to 55kb.

What the heck. Why, if I deleted all the cells outside that range in the first file, are the files not the same size???

I created the first file from a blank workbook, and its just a mockup for a new layout template for files at work.
There are no links, or anything but a small range where i entered dummy text and formatted a few cells (borders, font).

How exactly did you do that?
Did you press Delete on your keyboard, or Right Click - Delete, or Edit - Delete ?

Delete on the keyboard is not the same as other 2 methods.
It only clears the contents...

there is probably still a formula stored in the cells which would mean more data stored > larger file size
