Hi,
Actually, the second option is LocalSystem, not LocalService. LocalSystem is a very powerful account and has access to most folders and other resources on the system. User-specific folders are protected for a reason, tought, and you should use caution when exposing web applications having access to personal user folders. Hacking such web application would lead to much worse consequences than when NetworkService app is hacked.
As a workaround, you may grant NetworkService or LocalSystem access to the folder in question. Alternatively, please refer to
this post suggesting using ServicedComponent to elevate only part of the web application functionality, instead of the entire web application.
