Question: When running InSite I get an unexpected error that says “System.IO.IOException: The requested operation cannot be performed on a file with a user-mapped section open.”. What does this mean and how can I prevent it?
Answer: This error is caused by some anti-virus products. When InSite crawls your website it stores some information in temporary files on your hard drive. Some anti-virus products block access to these files while they are scanned, preventing InSite from reading them and causing this error message.
