Hello,
I am using CFNetwork to stream information to a file on an ftp site. Each time it makes a new file. Is there any way to just append information to the file if it already exists? I could read all the information in the existing file and then write the whole thing out again, but this would waste a lot of time uploading and downloading.

Have you tried setting kCFStreamPropertyFTPFileTransferOffset on your stream (before you open it). Don't forget to check kCFStreamPropertyFTPFileTransferOffset after the stream is ready as the server might not support (or not have enabled) this feature

Fred
