Make a copy of swapfile.sys to new location [File not found error]

Question

In PowerShell, I am trying to make a copy of the Windows swapfile (swapfile.sys)

PS C:\> Copy-Item swapfile.sys -Destination C:\Users\

However, I recieve the error:

Copy-Item : Cannot find path 'C:\swapfile.sys' because it does not exist.
At line:1 char:1
+ Copy-Item swapfile.sys -Destination C:\Users\
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (C:\swapfile.sys:String) [Copy-Item], ItemNotFoundException
    + FullyQualifiedErrorId : PathNotFound,Microsoft.PowerShell.Commands.CopyItemCommand

I can confirm the file exists with attrib *.sys

Perhaps this is due to the fact it is a hidden file, or a type of file that cannot be copied? I want to investigate this file with a HexEditor and was hoping to make a stand-alone copy for this.
