推荐答案

如果您正在通过网络工作到具有大量活动的目录，则filewatcher会导致大量网络流量。我一直在研究一个轮询的filewatcher，它在一个计时器滴答内运行，允许你确定检查间隔。我维护指定目录中的文件和时间戳列表。在下一个刻度线上，我将新列表与之前的列表进行比较。如果新列表中缺少某个文件，则删除该文件，如果新列表中的文件不在旧列表中，则添加该文件，如果文件时间戳不同，则文件已更改。对于我的应用程序，我发现15分钟的间隔就足够了。

If you are working across a network to a directory with lot's of activity filewatcher can cause heavy network traffic. I've been working on a polled filewatcher that is run from within a timer tick, allowing you to determine the check interval. I maintain a list of files and timestamps in the specified directory. On the next tick I compare the new list to the previous. If a file is missing from the new list it was deleted, if there is a file in the new list that was not in the old list it was added, and if the file timestamp is different the file was changed. For my application I find that a 15 minute interval is sufficient.
