Also, how are you gonna protect yourself against people uploading copyrighted contents?

Hopefully this will be a small problem. It's not a file sharing service, files are deleted automatically after 7 days, and if we get specific complaints we will delete them immediately.

What do you mean by "It's not a file sharing service"? Isn't this a service for sharing files?

I think he means that the link to the file is not intended to be public but restricted to your contacts only. People might use it as a sharing platform if they want to tho, I don't see what could prevent them to do so and that's why I asked the question in the first place. I'm sure that A sending a pirated file to B won't have a huge legal impact. But if A put this link on a forum and 5000 B's are accessing it... I think you should enforce some kind of download throttling to limit the access to the files. Or figure out something! I really do hope only right minded people will use it for noble purposes but come on, we both know that if your tool get some traction (and it looks really good so I dont see why it shouldn't) people will start messing with it and you won't be able to handle all the delete requests yourself!

Great idea, and it's pretty easy to do, X downloads max per file or X number of ips per file etc. This is really aimed at private 1-1 sharing.

Pretty Cool Stuff :)

Here are some observations & Questions :

1. Looks like you decide the number of chunks the file is divided into before you start uploading. How do you decide this ? (ie) the algorithm used ..is the chunk size a function of network's bandwidth & throughput . Or is it a standard chunk size ?

flowChunkNumber:6 flowChunkSize:512000 2. How do you generate the random file name ? I suppose this is one the standard algorithms. Curious

3.I suppose you are using statcounter & google analytics. What are some of the parameters you are looking at your end? (like #of files uploaded etc., )

4. Even if I change the name of the file (or) move the file to another location when the upload is inflight ; it still sucessfully continues to upload the originally intended file.Are you precaching this somewhere ? Is there a copy stored in the temp folder ?

5. What are you using to compress the files before they start upload ?

Yeah, that's what I figured. You probably don't want to throttle it too bad in case the same person got multiple computers (diff Ip's), but I think that something between a 100 and a 1000 could hit the right spot. And then depending on the feedback you get, you can work on implementing some better filtering. But at least it should dissuade people from making your tool the next megaupload :) I'd also work on throttling uploads of the same file, cause if you have a 100 DL limit per file then one can simply upload its file a thousand times and it will A) take a lot of space on your servers B) still be a pirate/sharing issue. Good luck and keep up the good work! :)

Thnak you, here are some answers :

1. Right now just chose something that made sense, need to test more 2. just randomly choose 7 chars a..zA..Z0..9 3. yes using both. right now still not looking into metrics 4. not sure, i'm using flowjs which is a library that supports this need to test further 5. I don't think files are compressed before upload.

Nice app. Plupload (https://github.com/moxiecode/plupload ) is an open source library that also allows you to upload large files. I've used it in projects before, such as a file explorer for Cloud Storage services (Box, Dropbox, etc.) that also allows for local file upload: http://jsfiddle.net/pseudonumos/PB565/embedded/result/
