Windows API Guide: CopyFile Function
Platforms: Win 32s, Win 95/98, Win NT
CopyFile copies a file from one location to another, just like copying a file in Windows Explorer or in some other way. Depending on the value for bFailIfExists, it will either overwrite the target file if it already exists, or will fail. The function retuns 1 if successful, or 0 if an error occured.
lpExistingFileNameThe source file; i.e., the file to copy from.
lpNewFileNameThe target file; i.e., the new file to create that will be the copy.
bFailIfExistsIf 0, the function will overwrite lpNewFileName if it already exists. If non-zero, the function will instead fail.

' Do not overwrite C:Junkbuffer.txt if it already exists.
Dim retval As Long ' return value
' copy the file
retval = CopyFile("C:MyStufftemp.txt", "C:Junkbuffer.txt", 1)
If retval = 0 Then ' failure
Debug.Print "Copy failed -- C:Junkbuffer.txt already exists.
Else ' success
Debug.Print "Copy succeeded."
End If;
