Why do people do this? Readmes and nfo files take up literal kilobytes.... even over hundreds or even thousands of downloads, at most it's going to take up a few extra megabytes of download/storage, they're not saving anything at all. And it can be nice when the nfo includes all the releaser's original encode settings and stuff.
For video files I always set it to download first and last parts of files first. You can watch a video fairly well with like 50% downloaded if the file has the first and last section, which contain the data about how the video is stored. It'll have occasional glitches, but it mostly works. At 99% it's effectively all there and you may not even notice that last 1%, let alone 0.1%.
