Help me : Cygwin refuses to create folder

Hi everyone. I've put this topic in "General Discussion" because I known this isn't a FB bug.

My current FB project uses ssh to connect and deploy files and folder.
SSH is beeing provided by cygwin, using private / public keys to connect.

In my FB flow, I first created directories to receive files, send the files, [rest of the flow...]

My problem is on my "create directories". The step shows no output (wich usually means folder have been created) but in the end, the folder is not created. So when I try to unzip (cygwin also) the files to the folder, I get an error saying "cannot create unzipping folder". But, when I take the exact same command line used to create the directories and run it from a cmd window, it works like a charm.

It seems that when using cmd from FB, cygwin refuses to create the directories but shows no error. Also, it seems the rights of the user is not getting used.

I use my user as "Run as" in FBServer, my user is admin everywhere. My user is running the cygserver (sshd) service. It is also my user who have the public / private keys.

Anyone can help ?

Thank you for reading this.

Update : I was able to make it work. I guess this was a combination of a lot of factors (rights on remote server, ssh config, etc.)
