This is most probably because usually a regular user usually does not have write permission in /usr/local/Wolfram. You could try whether that stuff will go there if you do it as root, but I don't think it will. I would expect that if you move those directories from /home/mike/.Mathematica to the correct directory within /usr/local/Wolfram that everything will work alright except when an update of the paclet is necessary... > I'm curious if anyone can tell me what makes this (or any given > information) go into .Mathematica in my directory vs the "system" > place. > > If it makes a difference, I'm using Mathematica 220.127.116.11 Home Edition on Fedora > 14 (32 bit) Unfortunately the paclet mechanism is hardly documented at all, there is no obvious or documented way to change that behavior (although I'm almost sure there is a possibility to change it). What you could do is to move the Paclet directory to a place of your choice, make sure you have read and write permissions there and then use a symbolic link in your /home/mike/.Mathematica which points to that location. I have not tested this but would be very surprised if it wouldn't work. You would then collect all the paclet data in a place which would not necessarily be in your personal backup. hth, albert
