The following example copies a file that is named OldFile from a folder that is named Old on drive C to a folder that is named New. If the file is copied, a message is displayed and the program continues. Otherwise, an error occurs. This example requires that you create the following variables in the C/AL Globals window. This example assumes that you have created the following file 'c:\Old\' OldFile.

Variable name	DataType
OldFile	Text
NewFile	Text

  
OldFile := 'old.txt';  
NewFile := 'new.txt';  
IF FILE.COPY('c:\Old\' + OldFile, 'c:\New\' + NewFile) THEN  
  // Continue your program.  
  MESSAGE('The file was copied.')  
ELSE  
  // Handle the error.  
  MESSAGE('The file was not copied.')
