Does anyone know of an algorithm for sorting extremely large files of linebreak-separated, case-sensitive ASCII values? I have a file that is 3,480,231kB of unsorted ASCII values, and I need it sorted... and, yes, I do have some idea of the time that this will take. I'm using WinXP for this, so win32 compatible utilities are a good thing for me. Thanks --Brendan -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
