Copies a file.

Note

This method is supported only in Business Central on-premises.

Syntax

[Ok := ]  File.Copy(FromName: Text, ToName: Text)

Note

This method can be invoked without specifying the data type name.

Parameters

FromName
 Type: Text
The name of the file that you want to make a copy of, including its path. When you enter the path, consider these shortcuts:

  • You can omit the drive designation if the file is located on the current drive.
  • You can omit the full path if the file is located in the current directory.
  • You can enter only the subdirectory name if the file is located in a subdirectory of the current directory.

ToName
 Type: Text
The name that you want to assign to the copy that includes its path. When you enter the path, consider these shortcuts:

  • You can omit the drive designation if the file is located on the current drive.
  • You can omit the full path if the file is located in the current directory.
  • You can enter only the subdirectory name if the file is located in a subdirectory of the current directory.

Return Value

[Optional] Ok
 Type: Boolean
true if the operation was successful; otherwise false. If you omit this optional return value and the operation does not execute successfully, a runtime error will occur.

Remarks

If you do not use the return value and the file cannot be copied, a run-time error will occur. If you do include the return value in your code, you must handle any errors yourself.

Example

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 assumes that you have created the following file 'c:\Old\' OldFile.

 var
    OldFile: Text;
    NewFile: Text;
begin
    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.');  
end;
