When booting from a Frugal Install, your application settings, bookmarks, etc can be saved to a hard drive partition, usb key, floppy, etc, in a file called backup.tar.gz. To create this file, right click on the desktop. System->Backup/Restore. Type in the name of the device to save to and hit backup. Then, when you reboot, your settings can be restored using the cheatcode
'dsl restore={hda1/sda1/fd0/floppy}'.
To change which files are saved, edit /opt/.filetool.lst (list of files to backup) and /opt/.xfiletool.lst (list of files to exclude from the backup process). Adding files to .filetool.lst can be easily done by choosing the file/dir in emelfm and clicking the 'Add2Filetool" button.
