With the new setup your UID has probably changed - the number used to
identify your username, it's in the  /etc/passwd file. It is always
sensible to keep the same UID's for your accounts across systems and
across installs - not sure how the wysiwyg/smart config tools help or
hinder this. I tend to edit the passwd file ! naughty though this is :-)

If you access the floppy as root you can get the files copy them and put
them back - they may not look as if they belong to you, use chown to
change ownership.

I just tar up and compress what I want to save and copy the file to some
other media, floppy/CD-RW/other comp on the network.

i.e. to save my home directory .......

   % cd ~
   % tar cfz . /tmp/home.tar.gz
   % mcopy /tmp/home.tar.gz a:
or % scp /tmp/home.tar.gz othercomp:/tmp/home.tar.gz

I usually extract the files into the tmp directory and copy across what I
want....

   % cd /tmp
   % mkdir me
   % cd me
   % tar xfz ../home.tar.gz

and then just copy across what is needed. AnOther option is to create a
sub directory in your new hoem directory.....

   % cd ~
   % mkdir from_old_computer
   % cd from_old_computer
   % tar xfz /tmp/home.tar.gz

hope that gives you some pointers.
