Create folder in Generic Setup Path

Question

Trying to create folder in filesystem. But it doesn't work for general domain users, only for admins.

I've tried

_strArticlePath = SPUtility.GetGenericSetupPath(Path.Combine(_strArticleStoragePath, strArticleId)); 



            SPUserToken sysToken = null;
            using (var spSite = new SPSite(SPContext.Current.Site.ID))
            {

                sysToken = GetSystemToken(spSite);

                using (var impersonatedSite = new SPSite(SPContext.Current.Site.ID, sysToken))
                {                      
                    using (var web = impersonatedSite.OpenWeb())
                    {                         
                        try
                        {
                            Directory.CreateDirectory(_strArticlePath);   
                        }
                        catch (Exception ex)
                        {
                            WriteLog("Create Directory", ex.Message);
                        }
                    }
                }
            }

and this one

        SPSecurity.RunWithElevatedPrivileges(delegate
            {
                using (var site = new SPSite(SPContext.Current.Site.ID))
                {
                    using (var impersonateWeb = site.OpenWeb(SPContext.Current.Web.ID))
                    {
                        impersonateWeb.AllowUnsafeUpdates = true;
                        Directory.CreateDirectory(_strArticlePath);
                    }
                }
            });

And both doesn't work. Advise pls.

First, keep in mind that letting non-admins create files/folders on the HDD is a risky security threat. I'm sure you can imagine. Second, SP is sort-of designed to be a better way to store files. So, in general, you are trying to do something that MS hoped you would not try to do.

The problem is most likely that you don't have the NTFS permissions set up on the HDD folder that you are working-in. Try setting the NTFS permissions (via file Explorer) to "Modify" for "domain users" or "Everyone" for the path (that you refer to as "_strArticleStoragePath").
