    For the Start-BitsTransfer cmdlet, assuming I have a $sourcepaths array and my destination is a single directory, is this a decent technique?

    $destarray = [System.Collections.ArrayList]::Repeat('C:\TEMP\',$sourcepaths.count)

    This is cool 👍, didn't know about Repeat() method.

    Yep, this will get you basically the same result as other methods in PowerShell would. Nice find, I hadn't known about this one either! 🙂

    Possible alternate methods:

    $destArray = (1..$sourcePaths.Count).ForEach{ "C:\TEMP" }
    $destArray = foreach ($N in 1..$sourcePaths.Count) { "C:\Temp" }

    Both of those will get you a standard array back, instead of an arraylist, however; so if you need the arraylist at the other end, use ::Repeat()

    That said, ArrayList is effectively deprecated, so I would recommend using List[PSObject] instead... although that initial list may need to be created via a LINQ enumerable expression first, as it seems List lacks the .Repeat() method itself.
