Paste after Clipboard.SetFileDropList produces: Packager cannot package empty files, error

[Academia]

I ran

Dim Strs As String() = Nothing
....fill Strs with file paths
DataO.SetData(DataFormats.FileDrop, True, Strs)
Clipboard.SetDataObject(DataO)

When I tried to paste into Wordpad I got
Packager cannot package empty files, error

so I rewrote it using
Dim fileCol As New Specialized.StringCollection
....add file paths tofileCol
Clipboard.SetFileDropList(fileCol)

But I got the same error.


What is "Packager"?

Is Wordpad running it?

If you have any insight as to what is going on I'd appreciate learning it.




Thanks
