I would like to see the following changes made to the backup/restore script (filetool.sh). Now the script backs up files and directories listed in filetool.lst and only excludes Cache. I would like to add the ability to exclude files or directories within the listed directories. To do that I added an exclusion file (xfiletool.lst) and added Cache to it. This would allow you to add the whole home directory of dsl and any other users to filetool.lst and exclude files inside them that are large and not changing by adding them to xfiletool.lst. One such file is XUL.mfasl under the .mozilla directory. If it is not there it gets recreated at runtime. Backing up that file adds upwards of .5MB to the backup file. It sometimes gets much larger. If you have added users and are backing up their home directories as well this can be huge. There are probably other files like this that others are aware of.

The following is the filetool.sh script. I commented out the original lines and
added my change directly below.
