Hello,
You can try this code:
Dim Users As String() = System.IO.Directory.GetDirectories("C:\Users\")
For i = 0 To Users.Length - 1
Try
My.Computer.FileSystem.CopyFile("C:\UserFiles\TestFiles\test.txt", "C:\Users\" & Users(i) & "\Desktop\test.txt", overwrite:=False)
Catch ex As Exception
End Try
Next
This code will copy the file to the desktop for each user. I hope it helps.
