Getting Directory Information Fast
By now, you may have noticed I’m always on the lookout for better performing code. This has turned out to be a good habit now that I’m working at athena health, as the pure scale of things is so much larger than places I’ve been at in the past. One piece I’ve never been able to speed up, though, is iterating through folders and files. Nicolas1847, a PowerShell scripter on Spiceworks, has come up with an ingenious method to get simple directory information using Robocopy (of all things), and a colleague at athena health likes to shell out to CMD.exe and use the old DIR command. But are they faster? And if so, which one?
