C# MVC Access to path denied when trying to write file

c# access-denied file-writing

I have an MVC application in which users are able to upload files. Before I write the uploaded file, I create a directory according to date time. I start off with C:\ApplicationName and end up with C:\ApplicationName\20111001\Filename.ext when the upload is completed (in theory).

My problem on my local Windows 7 machine is that I can not write the file.

I get an "access denied" exception no matter which user I give full access to the directory. The strange thing is that the date directory gets created just fine.

I have given the following users full access:

  • [Current logged in user]
  • NETWORK SERVICE
  • IUSR
  • IIS_IUSRS
  • Guests
  • Everyone

Without any success. I really don't understand what is going on here. When I give Everyone full access, I should be able to create a file right?

PS: I use Visual Studio 2010 and ASP.NET Development Server straight out of the box.

Check the permissions of the parent folder and make sure they are inheritable, you can check this on the advance options window.
