Hancom Sheet Questions, Why do saved file grow in size? Options

[GoLinux]

I have few very simple Excel files I have transferred to the SL-6000L. Their size is originally around 20kb. How is it possible that the size grow to more than 200kb after I open them in the Zaurus, make modifications like changing the columns width and text font and save them?

It looks also a little odd than when I try to open the modified file I get a warning message saying that the file is very large and it will take a while to open..... And in some cases it is several minutes.

I mean, the little beast can play video, open almost instantaneously large PDF files, run fairly complex programs, but considers "very large" a 200kb spreadsheet?

I know the issue is probably the way Hancom sheet deals with native Excel files and not with the Z per se, but still is quite annoying to have a powerhouse like the SL-6000L and not being able to work with a spredsheet!!!!!!

Any suggestions on how to solve the problem?

Thanks.
