I'd like to put a warning into my application that warns the user if they try to store their document inside the prefix/bottle. (In other words I want to help the user avoid putting user data under the "drive_c" folder.) I know that some folders are redirects, such as C:\Users\{user}\Desktop refers to the Desktop folder in the user's real profile, so this is safe, as well as many other special locations. Is there a command-line tool my app can call (running within Wine) that will convert any given path to the native path outside of Wine?
