Hi Mark, I've been away, but here are my comments to the draft: o The name "Streamlined FTP Command Extensions" reads very odd in my mind, as they are in fact new/additional commands, I don't see how they streamline anything. o RMDA - I think a 'rm -rf' version is a very good addition to FTP and it is in fact a generally requested operation by users in my experience. o DSIZ - I see very little value for DSIZ in practise. Since the size of a given number of files is only true in that very instant, the returned value will just be a reason for misunderstandings and misuse. The way the command is described is however accurate and functional. o AVBL - I see very little value for AVBL in practise. First off, this is only true the very moment the command is invoked and the next moment there may no longer be anything at all left so using the value for any logic will almost certainly be done wrongly. Further, disk space availibility depends on a lot of other factors as well besides just "available octets", så if there us 1000 bytes free you may be able to store a single 1000 byte file there, but perhaps not even be able to store 5 100 byte files. Alas, the value of such a command is questionable to me. o THMB - I am firmly against this command. The idea that we would promote a command that makes a thumbnail for an image file is an abonimation in my mind. That's not the job of FTP, the "File Transfer Protocol". If you need thumbnails for whatever file format, then provide them either directly as plain files in your file system, or write an FTP server that provides "virtual" files that you generate on demand when the client asks for the files. I strongly oppose this command. o CSID - fine with me. I don't see much benefit for many vendors to immediately start supporting it, but I don't see any harm in making a standard way to get/expose the information. -- / daniel.haxx.se
