Access to the path  C  inetpub wwwroot mysite images savehere  is denied   Read the message carefully   You are trying to save to a file that has the same name as the directory   That cannot work  you can t overwrite a directory filled with files with a single new file   That would cause undiagnosable data loss   Access to the path is denied  is the file system fighting back to prevent that from happening    The exception message is not ideal  but it comes straight from the OS and they are cast in stone   The framework often adds extra checks to generate better messages  but this is an expensive test on a network   Perf is a feature too    You need to use a name like  C  inetpub wwwroot mysite images savehere mumble jpg    Consider Path Combine   to reliably generate the path name

I was having the same problem while trying to create a file on the server  actually a file that is a copy from a template    Here s the complete error message    ERROR  08 07 2012 22 15 58 - System UnauthorizedAccessException  Access to the path  C  inetpub wwwroot SAvE Templates Cover pdf  is denied    I added a new folder called Templates inside the IIS app folder  One very important thing in my case is that I needed to give the Write  Gravar  permission for the IUSR user on that folder  You may also need to give Network Service and ASP NET v    the same Write permission     After doing this everything works as expected

I had the same problem but I fixed it by saving the file in a different location and then copying the file and pasting it in the location where I wanted it to be  I used the option to replace the the existing file and that did the trick for me  I know this is not the most efficient way but it works and takes less than 15 seconds

I had a lot of trouble with this  specifically related to my code running locally but when I needed to run it on IIS it was throwing this error   I found that adding a check to my code and letting the application create the folder on the first run fixed the issue without having to mess with the folders authorizations    something like this before you call your method that uses the folder  bool exists   System IO Directory Exists  mypath             if   exists              System IO Directory CreateDirectory  mypath

The following tip isn t an answer to this thread s original question  but might help some other users who end up on this webpage  after making the same stupid mistake I just did     I was attempting to get an ASP Net FileUpload control to upload it s file to a network address which contained a  hidden share   namely    MyNetworkServer c  SomeDirectoryOrOther  I didn t understand it   If I ran the webpage in Debug mode in Visual Studio  it d work fine   But when the project was deployed  and was running via an Application Pool user  it refused to find this network directory   I had checked which user my IIS site was running under  gave this user full permissions to this directory on the  MyNetworkServer  server  etc etc  but nothing worked   The reason  of course   is that only Administrators are able to  see  these hidden drive shares     My solution was simply to create a  normal  share to   MyNetworkServer SomeDirectoryOrOther  and this got rid of the  Access to the path    is denied  error   The FileUpload was able to successfully run the command  fileUpload SaveAs networkFilename     Hope this helps some other users who make the same mistake I did    Note also that if you re uploading large files  over 4Mb   then IIS7 requires that you modify the web config file in two places   Click on this link to read what you need to do  Uploading large files in ASP Net
