From IB tech (not sure, think it was Ernie) :
"The following files are where your data is stored on your machine;
jts.pg = your page file (symbols)
layout.lyt = your layout
exec.lyt = executution window layout
toolbar.lyt = toolbar layout
user.ini = user settings (window position, fonts, hot keys)
Easiest way to do this is to copy and paste the entire directory containing these files over the directory of the same name on the other machine. (c:\IBJts\dyrykq on one machine to c:\IBJts\dyrykg on the other)."
HTH,
