Default Word look alike?

In article , Neil

How is a 32-bit program going to manage a data block (with the document)
in memory that is over 4 GB in size? Yes, the program can, as you
implied, use a buffer to load part of the over 4 GB file into memory,
but, say, a search that scans the 4+ GB memory for the data block is
going to dump one buffer to move it into later bytes of the file. That
is for direct memory access to the file's contents.

The techniques used by professional graphics apps in the 1980s made the
size limitation of files based on disc size rather than memory.
PhotoStyler was one such app that only loaded the portion of the file
that filled the screen, and did so in a way that enabled detailed
editing on enlarged portions or viewing the full image at screen
resolution (which was minuscule by today's standards) without any
noticeable delay. After Adobe purchased PhotoStyler, mainly to eliminate
competition for PhotoShop which at the time was quite an inferior
product, they began integrating the programs methods and features into
PhotoShop. So, a 4GB file wouldn't be a problem.

quite a bit of revisionist history there.

photoshop implemented its own memory manager to handle larger images
before photostyler even existed due to the limitations of the hardware
at the time.

adobe purchased aldus for their entire portfolio, not specifically
photostyler, which wasn't in any way competition for photoshop.
