As per this comment:

I have a small application that gathers the size info and saves it into an array... but I often have half a million files, give or take and that takes a while to go through all of those files (I'm using FileInfo). I was just wondering if there was a faster way...

Since you're finding the length of so many files you're much more likely to benefit from parallelization than from trying to get the file size through another method. The FileInfo class should be good enough, and any improvements are likely to be small.

Parallelizing the file size requests, on the other hand, has the potential for significant improvements in speed. (Note that the degree of improvement will be largely based on your disk drive, not your processor, so results can vary greatly.)
