Grande link!
Ho un problema per il settaggio dei permessi alla cartella di Upload.
Mi viene visualizzato il seguente messaggio:

Error: Accesso al percorso "c:\inetpub\wwwroot\Project\Upload\Prova.rar" negato.

Ovviamete sarà un problema legato ai permessi.

Dovrei fare così ma non riesco a visualizzare il tab Security dalle proprietà della cartella Upload:

4. To change the security settings to grant write permissions to the Data directory, right-click Data, and then click Properties.
5. In the Data Properties dialog box, click the Security tab, and then click Add.
6. In the Select Users or Groups dialog box, click the ASPNET account, and then click Add. Click OK to close the Select Users or Groups dialog box.
7. Click the aspnet_wp account (computername\ASPNET) account, and then click to select the Allow check boxes for the following permissions:

• Read and Execute
• List Folder Contents
• Read
• Write

Click to clear any other Allow and Deny check boxes.
8. Click OK to close the Data Properties dialog box. You have successfully modified the Data directory permissions to accept user uploaded files.
