An existing zip file will be saved to a name and directory you select. Save To will not
replace or rename an existing zip file, but will create a copy of the
existing file with the new file name. As an example, if the current file
is "Backup.zip", Save To may create a new file "110393.zip" (a copy of
Backup.zip), but leave Backup.zip as it was. This will allow you to safely
delete and add files to one of the zip file copies without harming the other copy of the zip
file. Save To has to be done prior to the deletion and addition since
those choices perform immediate deletion and addition to the current zip
file.
