I am connecting to SFTP via host, port, username and password using PowerShell. I want to count the number of files in a particular zip folder without having to download the zip folder on my local machine and count. Please share the piece of logic that would do this. I looked into this but it seems a bit tricky when it comes to do this in a zip folder.
That's not an easy task to do. There's no API in SFTP to do that completely remotely. There are basically two solutions:
Use SFTP to download only the ZIP central directory (basically the listing that is placed at the very end of the ZIP file). And decode the directory locally. For C#, this is covered in my answer to List files inside ZIP file located on SFTP server in C#. Though as mentioned there, there's a bug in SSH.NET that requires a workaround with implementing an interface. While that's probably doable in PowerShell too, I've never done that.
If you have an SSH shell access to the server, use remote zip command to list the contents of the file. Or build another API (like a web service).
Btw, note that there's nothing like ZIP "folder". ZIP is an archive file. It's only Windows that call ZIP files "folders".

I have a problem with my VPS server, more precisely with extracting a .zip file (5GB) through the file manager. I have limited support because it is a self-managed VPS. I need a command for a terminal to extract file "5.zip" to a specific server dir for ex: http:xxxxxxx.com/funny folder on my server. Can someone help me with this? Thanks.
You provide URL, not path to directory. But to extract zip file in particular directory you can use command:
cd /directory/funny
unzip /path/to/5.zip
Change /directory/funny with the real directory which your web service serve.
We have a customer with their SFTP site, and I would like to copy files from specific folder, by using any automated process.
One of the example which I found, is winscp.net, but I have not managed how to use it, for my purpose.

QUESTION: All I will need is not run script and the file should be copied from their directory to my local folder. Is it possible at all?
I found the way of using PSFTP(Putty) to connect to the server, but how to make it automatically, do not know.
I think its a good solution for your problem.
You have to install winscp and the code some files and it will do automaticaly. I used 3 or 4 times. Also you need the key for your SFTP to connect throught it.
Here a link to the guide step by step.
https://winscp.net/eng/docs/guides
Here is a link to the scripting webpage
https://winscp.net/eng/docs/scripting
I recommend you to create an ini file to load all of the characteristics of your ftp connection and then execute an script over this.
It can be launched like that
WinSCP.com /ini=[your ini file] /script=[Your script file(what you want to do when it is connect)]
Hope this helps!.
I use the concept of uploading and downloading files from FTP server. I have been successful in both for a single file.
Now, for downloading, there may be more than one files on ftp. So, multiple files to be downloaded at local side.
I have referred this too, but couldn't get exactly what I want.
I want to download multiple files from ftp programatically. And for that I have to check the existence of file for particular URL.
Ftp protocal have the list cmd , you can list the files on the server and then download it.
I'm trying to think of a good solution for automating the deployment of my .NET website to the live server via FTP.
The problem with using a simple FTP deployment tool is that FTPing the files takes some time. If I FTP directly into the website application's folder, the website has to be taken down whilst I wait for the files to all be transferred. What I do instead is manually FTP to a seperate folder, then once the transfer is completed, manually copy and paste the files into the real website folder.
To automate this process I am faced with a number of challenges:
I don't want to FTP all the files - I only want to FTP those files that have been modified since the last deployment. So I need a program that can manage this.
The files should be FTPed to a seperate directory, then copy+pasted into the correct destination onces complete.
Correct security permissions need to be retained on the directories. If a directory is copied over, I need to be sure that the permissions will be retained (this could probably be solved by rerunning a script that applies the correct permissions).
So basically I think that the tool that I'm looking for would do a FTP sync via a temporary directory.
Are there any tools that can manage these requirements in a reliable way?
I would prefer to use rsync for this purpose. But seems you are using windows OS here, some more effort is needed, cygwin stuff or something alike.
I am having a lot of issues trying to automate downloading from an ftp site. I know the folder the file will be in, and I know that it will be a .zip file. However I do not know what the files will be named.
So I have code that works if I know the file name...for example:
$sourceuri = "ftp://myFtpSite/test/myZipFile.zip"
I would like to be able to use wildcards in this string so it will recongize any zip file. So I could write something like
$sourceuri = "ftp://myFtpSite/test/_.zip"
and it would download any zip file in that folder.
I know this question is ancient, but have you considered just using the console app ftp.exe? You can build a text file with commands (such as "mget *.zip" to retrieve all .zip files) and automate the process.
