I'm not sure that's true. Computers used to be smaller, and had a hard time with very large files. Swapping out of limited RAM and so forth. Not fast. I think long files are solely caused by somebody incapable of software design at any level. They just keep typing and never think about structure or separation of duties or whatever. I recall the WindowsCE DHCP service was one large file. An enormous busted-ass straightline pile of garbage code that didn't handle most errors. Written by some intern. I re-wrote it for our platform and removed all the issues. Microsoft of course didn't want my code because, arrogance.
