How about using SHFileOperation?

Data

SHFileOp LIKE(SHFILEOPgroup)
Source CSTRING(256)
Destination CSTRING(256)

==========

Insert this where you want to perform the copy:

! This copies an entire directory - note the terminating <0>
Source = 'C:\TheSourceDirectory\*.*' & '<0>'
! This would copy 2 files
! The filenames are separated by <0>
! The list is terminated by <0><0>
Source = 'file1.exe<0>file2.exe<0><0>
Destination = 'C:\TheDestinationDirectory'

CLEAR(SHFileOp)
SHFileOp.hWnd   = 0{PROP:Handle}
SHFileOp.wFunc  = FO_COPY
SHFileOp.pFROM  = ADDRESS(Source)
SHFileOp.pTo    = ADDRESS(Destination)
SHFileOp.fFlags = FOF_NOCONFIRMATION + FOF_NOCONFIRMMKDIR

SHFileOperation(ADDRESS(SHFileOp))
