at 11:30 - each line of that file becomes an object - but the String object, and not the File object, right? Since I checked it with Get-Member cmdlet, they had different set of members.

I think he needs to clarify something a little better. At the end, when he says "if we look at the help copy-item -full" and says the "SOURCE" parameter accepts pipeline input, he means the -Path parameter. This hung me up for a long time! The word "Source" is nowhere. It should be assumed to be the -Path. It wouldn't have been so hard to understand if he would have clarified that. Otherwise, great tutorial.

I came across the problem that some commands can automagically work on multiple pipeline objects while some need a for loop.
This is because of the type of output and input that objects create.
I encountered this when I was trying to pipe a list of filenames into copy-item

Can you tell me.. in a pipeline if a GPS | sort .. do all the output of GPS goes to the next pipeline or it will go one by one.

Thanks in advance
