I am trying to modify an xml file from my aspx code. The file is in another directory from my project like in D:\folder\file.xml When publishing my code and running it I am receiving an error as not to be able to access this directory, access in denied. Which user account shall I add to this folder in security option to be able to modify it. I tried adding IIS user but it does not seem to work. Any other workaround this ?
Check which identity that's associated with the application pool, and grant that user access to the folder.
You didn't specify which version of IIS you're using, but here's a decent article on how application pools work
