Quick, practical summary for copying files in VB6 (adds concrete examples to the brief replies above). asked for a simple example; pointed toward scripting, and mentioned a helpful attachment. Below are three common approaches, when to use each, and small, ready-to-run snippets.

Built-in one-liner (simple single-file copy)

On Error GoTo ErrHandler
FileCopy "C:\path\source.txt", "C:\path\dest.txt"
Exit Sub

ErrHandler:
MsgBox "Copy failed: " & Err.Description

Scripting.FileSystemObject (flexible, supports wildcards and folders)

' late binding — no reference needed
Dim fso As Object
Set fso = CreateObject("Scripting.FileSystemObject")
fso.CopyFile "C:\folder\*.txt", "D:\backup\", True

If you prefer early binding add Project->References->Microsoft Scripting Runtime and declare Dim fso As New Scripting.FileSystemObject.

Windows API (low-level, returns Win32 error codes)

Declare Function CopyFile Lib "kernel32" Alias "CopyFileA" _
    (ByVal lpExistingFileName As String, ByVal lpNewFileName As String, _
     ByVal bFailIfExists As Long) As Long

If CopyFile("C:\a.txt", "C:\b.txt", 0) = 0 Then
    MsgBox "Copy failed. Error code: " & Err.LastDllError
End If

Quick gotchas and tips

  • FileCopy and FSO require the destination folder to exist; create it first (MkDir or FSO.CreateFolder).
  • Watch file locks, permissions and UNC paths on networks.
  • For large-file progress or resume, read/write in chunks or use shell APIs designed for user feedback.
  • Always catch errors and use full paths to avoid surprising results.

These three patterns cover nearly every VB6 copying need. Choose FileCopy for simplicity, FSO for convenience (wildcards/folders), and the API when you need native error codes or more control.

The attachment covers all about copying and pasting of files as well as saving the link to a database.
