Can FTP Folder be outside of ASP.NET Web Application

I currently have a classic ASP website with a root folder called \FTP. I've built a new ASP.NET web app that will copy files from that folder to one that is part of the ASP.NET web app directory structure. Unfortunately, in my production environment, I have to make the web app a subfolder of the root folder. So my structure will be as follows:

\FTP
\MyWebApp
MyWebPage.aspx
\FTP_Processing_Folder

Because of permission issues, I assume my web app won't be able to access the files in \FTP. Is that correct?

If that is correct, can I just design my folder structure to have the FTP folder inside the web app as follows:


\MyWebApp
MyWebPage.aspx

\FTP \FTP_Processing_Folder

where only \FTP will be set up for FTP file uploads. Is this correct?

Lastly, are there any special permission issues I need to worry about with regards to the FTP folder other than to make sure that ASP.NET can access the folder and that FTP users can only access the FTP folder?

Thanks in advance.
