joining large text files

i need a simple script or perhaps there is already a command in the shell to append/join one lare text file to another. we are talking a good few GB of data. I tried doing it in primalscript but it just crashes out when i paste in the other file. Any ideas how to do this?

Why not use a simple copy command :
 copy largefile.txt+largefiletoappend.txt largefile.txt

You can do this via the command line using the type command...

Type c:\file1.txt >> c:\biggerfile.txt
Type c:\file2.txt >> c:\biggerfile.txt

Remember to put "" round the file name if there are spaces.

Copy should be fine as has already been suggested or you can use a single type line too, though I suspect this would be slower.

type c:\source\*.txt > c:\dest\allfile.txt

cd /d c:\source
type file1.txt file2.txt > c:\dest\allfile.txt
