64Bit native software for Windows 8

    Yeah, not trying to argue about things, just discussing. A 300MB file wouldn't fall into the large dataset area and a 32bit version of Office could handle this no problem.

    I just like to make sure people who believe that 64bit will be much faster or handle much larger files realize just how big of a file we are talking about before that large file size benefit comes into play.

    But do you know how big that file would approximately be? I'm don't.

    I will check next time I go to a customer who use them, I always told them it's not a good way to do thing.

    Theoretically any data file will do for testing. I use 32bit Office on the pc I'm now and tried a small test.

    I loaded, just for the show, a 7z archive into Excel 2007 x86 to see how much memory it uses:
    file = 88mb
    loaded excel in RAM memory = 254mb

    So loaded, it uses much more memory.
    Rule of thumb:
    A 300mb file on x86 uses about 866mb RAM. (this will be more RAM on x64, area66 can confirm perhaps?)
    Only above 2gb ram usage (700mb file) for 32bit Excel will be problematic.

    This is just an estimation, maybe some memory tricks are applied for big files.
    But what's sure is that the x64 Office can go beyond this limits easily.
    More importantly is that the x64 Office will use more memory for the same file sizes compared to the 32bit version. This was concluded after seeing many 32bit programs and their x64 counterparts in action, and I think it's a general rule.
