I have been using TFileStream objects in my application, but have got problems whith files greater than 2 GBytes as Size, Seek etc use LongInt !

Can anyone think of a way around this. I suppose all I really need is a way of determining the size and setting the possition as an Int64!

Thanks for any help,
  Dave Taylor.
