    Not sure what you mean by run on”domain”. The error is pretty clear, the file access is denied. If h: is a network drive, then be sure it’s mounted under the user profile the app is running under.

    Your app is trying to access a protected system folder:

    H:\System Volume Information- this is a restricted windows folder, and even administrators don’t have access to it by default.

    You can try these solutions:

    1.      Skip Restricted Paths in Code

    Update your code to skip or catch error when accessing restricted directories:

    Try

    {

                    Var files=Directory.GetFiles(path, «  *«, enumerationOptions) ;

                    //Continue processing files

    }

    Catch (UnauthorizedAccessException ex)  

    {

                    //Log or ignore the folder

    Console.WriteLine($ »Access denied to folder : {path} ») ;

     

    }

     

     

    You can also pre-check the folder name:

    If(!path.Contains(“System Volume Information”))

    {

                    //proceed to scan

    }

    2.      Run the app as administrator

    3.      Filter Input Paths

    If you’re allowing users to select drives or directories, avoid hidden/system folder unless explicitly needed. Use DirectoryInfo.Attributes to filter:

    Var dirInfo = new DirectoryInfo(path);

    If(!dirInfo.Attributes.HasFlag(FileAttributes.System))

    {

    //safe to scan

    }

     

    Hope this helps. Please try this and let me know for more query?
