TMemoryStream
provides an in-memory buffer, so if you download into one, you need to have enough memory to hold everything you receive. It's not the only kind of stream, though. You can pass the Get
method any kind of stream you want, including one that writes its contents to disk as it receives it. Use TFileStream
, for example.
var
s: TStream;
s := TFileStream.Create('myfile.zip', fmCreate);
try
IdHttp1.Get(..., s);
finally
s.Free;
end;
Anywhere you call LoadFromFile
or SaveToFile
on a TMemoryStream
, it's possible that TFileStream
is a better choice.
