How to know when a file is fully uploaded

[adu]

External users upload large file on my FTP (>1gb) and I want to be able to download it as soon as that file is fully upoaded.
Is there a way to ask Yummy to download a folder and its content only when that content is not still being transferred on the ftp?
Can we start a download of a file that is still being transferred on the ftp? What will happend if the download is quicker than the file upload?
This is really useful to optimise the production flow and avoid waiting hours before starting to download new file from the ftp.

Thanks for your suggestions.

There's nothing in Yummy that will allow you to this right now - it's basically a reverse of the current FTP Watcher feature. It's been asked for before, it's possible to do, and it's on my To Do list.

Downloading a file while it is still being uploaded will lead to unpredictable results. Don't do that.

One idea is for your Mac external users to use Yummy's FTP Alias feature in conjunction with Growl (www.growl.info) to do thier uploads to you - the FTP Alias can send you an email notification via the Growl notification system when the upload completes. For PC users, there are lots of FTP clients that can send an email when finished.

Another suggestion would be to use PureFTPd as your FTP server - it uses a hidden temporary file while the upload is in progress and  shows the file in the directory list only when it is completed. You could then use Yummy's scheduled Synchronization to run once a minute and download whataver is new.

Hope that helps
