Why I don’t trust Windows copy for big files—and what I use instead now

Copying around a couple of small files, like screenshots or documents, is, for the most part, normally fine. They’re normally small files, and you won’t have much trouble moving them around. The problem, however, comes when you actually have to move around a file that’s several gigabytes in size, or worse, several of them—using the regular tools meant for that purpose, your PC will be struggling.
