I made backups of both files in each computer and rsync dealt with it as 
long as I transferred the entire file, something I could have done with 
sftp. If I tried to rsync the larger file with the smaller it simply 
replaced the larger file and I lost information.

What I did not realize is that the "notecase" files are in html:

    <!DOCTYPE NoteCase-File>
    <!--LastNote:83-->
    <HTML>
    <HEAD>
    <meta content="text/html;charset=UTF-8" http-equiv="Content-Type">
    <meta name="generator" content="NoteCase 1.6.1">
    <TITLE></TITLE>
    ... snip ...

Which leads me to believe that's a format rsync can't deal with or 
requires different "options" other than the -av I used?

So I have the same information in both computers but there is data in 
the smaller file that I do not have in the larger one. I may have to 
copy the data individually which will probably work all right but there 
is no assurance that I will get everything.

I will deal with my note keeping differently in the future.

I also have calendar data in "remind" that I need to do a similar 
operation on. It looks like I've painted myself into a corner?
