The "loss" we keep discussing is one that arises from the compression
that takes place when saving the file. If, while editing a file, you
keep saving it, you are not causing incremental damage to the file as
you don't keep closing the file and re-opening it. The damage you
cause the file while editing is purely from the editing and will take
place whatever the final format.
I suppose you might say that the file does not have a format, per se,
while it is sitting in memory on your computer. It takes on a format
(one which you choose) on the storage medium you are using when you
save it, whether for the first time or umpteenth time.
Some programmes don't touch the original file but operate on a copy
(perhaps called "filename-edit") while you conduct editing
operations. When you come to save (or "export"), the operation is a
completely new save operation which can be under a different name.
