Check if a file exists?

[Lop]

Similar to the C++ thread, how can I check if a file exists in Delphi?

[BuildPromoteWin]

It is the FileExists() function.

Here is a code sample from the help file to check if a file exists and then prompts for confirmation before deleting it:

if FileExists(FileName) then
  if MessageDlg('Do you really want to delete ' + ExtractFileName(FileName) + '?'), mtConfirmation, [mbYes, mbNo], 0, mbNo) = IDYes then 
    DeleteFile(FileName);

Use FileExists function. If file exists, then this function will return True.

procedure TForm1.Button1Click(Sender: TObject);
begin
if FileExists(Edit1.Text) then
ShowMessage('File already exists!')
else
ShowMessage('This file is unique');
end;
