Thanks a bunch for your Quick reply.
Dang Strawberry is indeed 32bit.. Dang...
I need to the the big files as is as they are dumps of file systems/registry/memory and I need a Diff of 'em.
So if I do Line by line I get the problem that it won't find the extra inserted lines it will see everything wrong after an insert.
So its deeper then line by line. Is there a way to still do this? I ported this from C as I had a little issue with my LCS Algorithm..
