Example 77 with OCFile

/**
 * /**
 * Scans the default location for saving local copies of files searching for
 * a 'lost' file with the same full name as the {@link OCFile} received as
 * parameter.
 * <p>
 * This method helps to keep linked local copies of the files when the app is uninstalled, and then
 * reinstalled in the device. OR after the cache of the app was deleted in system settings.
 * <p>
 * The method is assuming that all the local changes in the file where synchronized in the past. This is dangerous,
 * but assuming the contrary could lead to massive unnecessary synchronizations of downloaded file after deleting
 * the app cache.
 * <p>
 * This should be changed in the near future to avoid any chance of data loss, but we need to add some options
 * to limit hard automatic synchronizations to wifi, unless the user wants otherwise.
 *
 * @param file File to associate a possible 'lost' local file.
