Saving Excel Files to CD-RW

[mekkor]

For some years now I've been able to insert a CD-RW disc, double click on an Excel file stored there, open the file, edit the file, then simply resave the file under the same file name back onto the CD-RW disc.

Seemingly, suddenly I am no longer able to do that.  Now when I double click on the Excel file, it opens as "Read Only".  After I make my edits, the system wants me to save under a new file name because the file is "Read Only".  When I do that, the system now "saves" the file to a temporary burn folder rather than writing the file to the disc.  I then burn the file to the disc and a new file is added under the new name.

I could probably handle the extra step of burning the file to the CD-RW everytime but I simply want to overwrite the previous file, not fill up the disc with new files everytime.

How do I get back to inserting the disc, opening the file, editing the file and saving the file to the disc, then being able to repeat all of that but rewriting the file not creating a new one everytime?  I'm sure that I am missing something fundamental in how writing to CD-RWs works.

Thank you.

Why not use a USB thumb drive, and avoid the hassles?

Because thumb drives in my house tend to disappear into kid's backpacks to take to school for projects.  I can't keep enough thumb drives around.  CD-RWs do not cost as much plus they don't seem to "walk off" as much.  T

hat plus I was hoping to learn something about why CD-RWs do or do not work the same thumb or any other kind of storage drives.
