This Shell32 routine copies all files between the source and destination directories:

LOCAL oShell, oSrcFolder, oDstFolder

oShell = CREATEOBJECT("Shell.Application")
oSrcFolder = oShell.NameSpace("c:\temp1")
oDstFolder = oShell.NameSpace("c:\temp")

IF VARTYPE(oDstFolder)="O" AND VARTYPE(oSrcFolder.Items)="O"
        oDstFolder.CopyHere(oSrcFolder.Items)
ENDIF

The table may stay open in the source directory, it is still being copied. Though need to test it in all modes; for example, how does it work when the source table has uncofirmed changes.
