Re: [twsocket] FTP resuming transfers
Its possible that a client can rollback some part of the file incase the end (where the transfer was interrupted) is corrupt. Some clients do a REST to eg. 4kb less than the current size. I think it makes more sense to set the position and size when the transfer begins following a REST command.

I think that I don't undestand why you have to set the size of the TFileStream when it is destroyed. Do you mean it could be smaller than his previous size when resuming a transfert ?

Re: [twsocket] FTP resuming transfers
Yes, I believe you can safely set the Size property manually as a workaround. That's what I do!
