PalmSaver is an easy solution to create up to five compressed backups (*.arj or *.zip), including folder info (paths), of your Palm User-Directory. Each Backup can be opened with the associated Packer (e.g. WinRar, WinZip) and deleted from PalmSaver's Main-Window. The oldest Backup will be deleted each time a new Backup is added.
