Apple Newton Backup Utility (for Windows) - Manual (Page 16)

Backing up cards
When you back up a storage card, a separate backup file is created with the name of
the card. If you haven’t entered a name for your card, the file is called CARD. If you
back up more than one unnamed card, the backup files are named CARD.NBK,
CARD2.NBK, CARD3.NBK, and so on.
Note: You should name all your storage cards. For more information on naming
storage cards, see the handbook that came with your Newton PDA.
Previous backups
Every time you back up, the Newton Backup Utility makes a copy of the previous
backup file and stores it in a directory called PREVIOUS. This directory is located
in your BACKUPS directory.
For example, if your Newton PDA is named Newton, the Newton Backup Utility
creates a file named NEWTON.NBK the first time you back up. The next time you
back up, the Newton Backup Utility copies the original NEWTON.NBK file and
places it in the PREVIOUS directory.
The Newton Backup Utility maintains a current and previous backup file for all
information in your Newton PDA’s internal memory and a current and previous
backup file for each storage card you back up.
