Filezilla, automatic mail generation

Exactly. We are using Filezilla as our ftp server. Your understanding is correct.  I need to monitor one folder and its subfolders as you correctly understood. Anyone of a group when put any file in any of the subfolders, each member should get an email confirmation from his mail account regarding that update.

I think you are very right. I need to do this either by program or script. Windows is ftp server os.

One thing I must point out, Filezilla server is given by our ISP. They will not allow me to scripting on their servers I think. The program or script should run from clients pcs.

Unless you can run the monitoring at the server side, this will not work very well. The reason is, you can write a script to scan and catalog the file system on a local machine and do it every few minutes. The load would be minimal and there would be no network load at all unless the emails were being sent out. If you tried to do this from the client side, the program would have to download a catalog of files in each folder at some frequency which would cause a lot of network traffic. Now multiply this by every user that would be needing to do this. That is a whole lot of network traffic.

Alternative, do you have a webserver on the same server? If so, write a web based tool to monitor the FTP folders and do it locally.

No I have no webserver. But I think I can setup an iis server if you help me. Else I have no problem in network traffic volume. I am comfortable with any winform program. If you give me idea, I can do this. I have no exposure in web form or web service. I have little knowledge about Filezilla,  thats a problem to me also.

I am not certain this is as simple as a few questions. On the client side, have you ever written any code to do FTP connections? I think the complexity of this would be greater than the rewards. That is what you will have to do if you want it running client side.

Server side, I cannot assist you with installing IIS but if you can get it done, it would be an easier task to write an ASP.NET project in wither VB or C# to iterate the folders you want to monitor and then send an email.

I can not do anything in Filezilla server. I can set up a iis server in my office. Will it work?

Filezilla server is at ISP location.  Not in my scope of job

Client side app looks like your only option

Yes, from your comments I also think so

Now my query comes to, how can I connect and search folders of Filezilla server from client side application? Right?

Yes, since you seem to only have FTP access to the server, your local application would need to programatically make an FTP connection and then iterate through the current directories, store a cached list of file names with timestamps. After a period of time, do it again but compare the previous run with the current run list of files and send a notice if something has changed.

Robo-ftp seems a very nice choice. But I do not think our client will change their ftp for this purpose.  They are using Filezilla for many days.

if I want to log on and iterate with the admin account of that Filezilla server from c# or vb.net, what will be the syntax? I never connected ftp through winform. Please help

Yesssss, its a very nice idea. But is it possible? How it can be merged?

What do you mean by: "How it can be merged?"

Sorry for my stupid question :-). Can you please explain a little more? I am not clear fully. Your solution seems to be very realistic and interesting for me. Please elaborate a little bit more.

Robo-ftp is priced, i think. I think coding in client is the only free solution?

Thank you for your suggestions
