It is possible to read/write files that have longer paths than 260 characters if you use UNC paths by prefixing absolute paths with "\\?\" on Windows. For executing files on Windows we can improve the situation by using a combination of UNC paths together with GetShortPathNameW before sending the path to CreateProcessW. Only restriction here is that the resulting shorted path must still be shorter than 260 characters.
