If the files are all PDF, then pdftk can easily join them in another
PDF. For Postscript, they can easily be converted to PDF and then
joined.
I believe there was a KDE extension that allowed some pdftk
operations in an "easy" graphical way. But I do not remember in which
package it was.
Second to pdftk. I use it all the time.
e.g.
pdftk p1.pdf p2.pdf p3.pdf cat output p_combined.pdf
pdftk has a really nice minimal syntax, compared with Ghostscript.
gs -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=out.pdf in1.pdf
in2.pdf in3.pdf
