Limited file details

What I found out is that the Shell Namespace API does not provide a lot of details of the file. It is limited to only a couple of fields that are relevant for the Windows Explorer GUI. Strangely, a byte-oriented filesize field is not part of it. It only contains a summarized version, e.g. 4 kB or 10 MB. After futher investigation, I noticed that Windows Explorer has to make a local temporary copy to get all the details in order to populate the information pane. That's why most operations are so slow!

I think you need to change
$android.GetFolder()
to
$android.GetFolder
It's a property, not a method. (though its name implies otherwise)

hello,
really good job.
Please can you help me ?
I am trying to copy files from ssfDRIVES to my computer.
It's a file on 'MY PC\Bebop 2\Media" (a drone) that i want to transfert to my computer
Using $item.path in your script, i found the path of the file is :
::{20D04FE0-3AEA-1069-A2D8-08002B30309D}\?\usb#vid_19cf&pid_5038#pi040436aa7j016983#{6ac27878-a6fa-4155-ba85-f98f491d4f33}\SID-{10001,,7695343616}{00530071-0048-0006-0600-1D007A0794D7}
if i try to use copy-item, a get error because PS can't find "c:\Users\mylogin::{20D04FE0-3AEA-1069-A2D8-08002B30309D}"

Thanks in advance for your help
