I found a very old AutoIt script for obtaining file version information (Properties > Details items like the version string, product name, copyright, etc.). It didn't work very well, so I rewrote it after I discovered FileGetVersion(). The problem is that FileGetVersion() is returning outdated information that seems to belong to an old version of the file, long after the file has been deleted and recreated. Windows Explorer, on the other hand, shows up-to-date version info in the Properties > Details tab because (I think) it's accessing the cached file metadata and/or the latest version of the file. This looks similar to the Windows behavior in which (e.g.) the modification time for a previous incarnation of a file is still displayed by dir even after the file has been deleted and recreated. The timestamp is updated eventually, but in my case "eventually" is approaching infinity. Is there a way in AutoIt to force retrieval of the latest file version properties? Failing that, is there some external method (like a command or admin setting) that can force Windows to return the latest version info when requested by a program?
