We're not talking DOS either. Windows 98 might've written data synchronously to USB devices, but with flash having limited erase/program cycles[1], modern operating systems[2] stores a cache of data to be written to the device. This is only written to the storage device: - if the `sync` command is run - if the device is unmounted - when sufficient data is in the cache to make a write worthwhile - if mounted with the 'sync' option: on every write Unless you've configured your system to mount the filesystem with -o sync, assuming that hitting save in your application means the file's written to disk right there and then is a very dangerous assumption to make, and one that will bite you hard in the bum some day.
