If you're up to date in VFP versions, using the FileToStr() function can greatly simplify copying individual files, as follows:

lcFileContent = FileToStr (thisfile)  IF LEN (lcFileContent) > 0      
   StrToFile (lcFileContent, odrFileName, .T.)   && Final parameter means append to file.

   &&   0 length indicates either an empty file or an error attempting to open.
ENDIF
