Allway Sync是一个非常容易使用的 Windows 文件同步软件。
它可以在几个文件夹之间进行文件同步。
同步方式有源文件夹同步和各向同步两种方式：一、源文件夹同步方式将以一个文件夹为基准，删除或覆盖其余文件夹与源文件相比较不相同的文件。
二、各向同步方式则自动将更新的文件覆盖几个同步文件夹中的旧文件。
软件带有一个小型数据库，监视每次更新后的文件状态。
如果在一次同步之后，你删除了同步文件夹中某些文件，它在同步的时候将其它的几个文件夹的副本也删除，而不会将不需要的未删除文件重复拷贝到已更新的文件夹。
由于软件自己会对文件进行删除和覆盖，它提供了使用回收站进行文件备份的措施，使用者可以在不慎执行错误的同步动作之后，从回收站将错误删除或覆盖的文件找回来（默认禁用该功能，请到软件选项处激活相应设置）。
此外，该软件还具有自动同步功能，可以在指定的条件下自动执行同步任务。
该软件还可以通过指定文件筛选列表，过滤一些不希望同步的文件或文件夹。
