Net Date/Time objects, but some other format. So the dates that are in the file system object are not. When the file system was original created many of the object types that we use every day didn’t exist.

Too much data! This isn’t really a problem so much as a consequence of what the cmdlet is doing.

Net file handling classes, which don’t support long files names–so nothing more than 260 characters in length. This might be your first question, and it’s a really good one! The core problem is Get-ChildItem isn’t the most performant cmdlet in your PowerShell toolkit, and let me outline a couple of problems with it. But are they faster? And if so, which one? 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.

One piece I’ve never been able to speed up, though, is iterating through folders and files.

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. By now, you may have noticed I’m always on the lookout for better performing code.

Robocopy faster
