What is the PowerShell syntax?

What is the syntax of the Copy-Item cmdlet to copy/mirror the C:\Users\Me folder on an external SSD folder D:\MeMirror ?

I rarely say this but google it!

The syntax of such cmdlets is often quite complicated and too much for users to summarise in a post.

Here I did some leg-work by googling "copy-item cmdlet" for you.

@cerberus Thanks, I should have known that there was a pertinent microsoft docs item (I got confused by some 'ultimate guide', the microsoft docs item is much, much clearer)

After trying out some cmdlets, the most purposeful for me is

Copy-Item -Path "C:\Users\Me\*" -Destination "D:\MeCopy" -Recurse

The cmdlet needs to be run twice, the first run is to establish the directory. It creates a copy that also captures additions and changes to files in subsequent runs, but it does not delete files, i.e. it is not a true mirror. It also creates the Junctions inside the My Documents folder (My Music, My Pictures, My Videos) but the subfolders are empty, i.e. PowerShell is smart enough not to duplicate, so there is no need for any exclusion (which does not appear to be possible either)

I am still testing things

The cmdlet below preserves the time stamps of the files, but not the time stamps of the folders.

Copy-Item -Path "C:\Users\Me\*" -Destination "D:\MeCopy" -Recurse

How do I preserve the time stamps of the folders?
