Yes. Actually, you can open that file and start reading it in Perl and open files to write out the chunks the way you want them. Then close each. Make up a name with a counter in it to create all the many files of chunks. Suck off some data/statistics and accumulate info you want as you go. You could even decide some of it isn't worth keeping and cut the size of your chunks down if you don't need all of it. But, you would have to close each of those chunk files or you would run out of space for open files. So, there would have to be a counter loop to keep track of how much was written to each chunk and an open and close for each one. ////jerry > > -- > CCD CopyWrite Chad Perrin [ http://ccd.apotheon.org ] > Kent Beck: "I always knew that one day Smalltalk would replace Java.
