I want to upload the file into a folder which is outside of the root whose path will be specified in webconfig path can be in any drive of the system. I want to read the value from web config.

I need to hardcode the path like: D:\somefolder\FileUploadFolder

my webconfig file is
<add key="FileUploadFolder" value="D:\somefolder\FileUploadFolder"/>
string folder_from_config = ConfigurationManager.AppSettings["FileUploadFolder"].ToString();
FileUpload1.SaveAs(folder_from_config + "\\" + System.IO.Path.GetFileName(FileUpload1.FileName));
am getting error like
 same error is" 'c:\somefolder\FileUploadFolder\sheet.xls' not a valid virtual path."

Does IIS has the permissions to write to that folder?

as per my knowledge you cant store the file out of your IIS server folder(virtual directory).

Hi, You need not use System.IO.Path.GetFileName. You can directly save the file in the specified location.

string fileName = FileUpload1.FileName;
string fileDest = folder_from_config + "\\" + fileName;


Will solve your problem. Good luck..!

You can't save an uploaded file to any folder that isn't a virtual folder defined inside IIS. Generally, it's bad practice to save/load files OUTSIDE of the website's folder hierarchy.
