Title: An easier function to get a file's Size.
Question: How to retrieve a file's size given it's name, no handle asked ;-)
Answer:
I have written this small, little and very fast function that returns the size of a file, given the name and path.
If the file doesn't exists, it returns -1 instead of the file's size, so you can also catch errors in passing the filename.
//========================================================
function GetFileSize(FileName: String): Integer;
var
FS: TFileStream;
begin
try
FS := TFileStream.Create(Filename, fmOpenRead);
except
Result := -1;
end;
if Result -1 then Result := FS.Size;
FS.Free;
end;
//========================================================
==========================================================
Example of use:
==========================================================
procedure TForm1.FormCreate(Sender: TObject);
begin
ShowMessage(IntToStr(GetFileSize('c:\prova.pdf')));
end;
