刚才一不小心把一个星期写的代码全删除了，因为放在了一个文件夹下面，而用php删除这个文件夹下的其他文件，没整好，结果整个文件夹全没了，，那个悔啊！！
幸好我用的是Eclipse，右键工程=>restore from local history。可是只能回复一些，不全。想起以前用的R-studio，还是这东西好用啊，很轻松就把删掉的文件恢复了。

tips：文件被删除以后千万别动了，千万不要再操作Eclipse了，比我当文件被删除，但是还打开着编辑面板，切换过去会说什么文件不同步了，问你是不是刷新，要是傻乎乎的按F5刷新，那一下子就杯具了，因为Eclipse有可能会从写。我那个文件虽然后来用r-studio恢复了，但是内容却被Eclipse重写了。

大家看看，多杯具。
所以，千万别做任何操作，立马用R-studio恢复。基本ok
附：r-studio 下载地址和注册码

建议：即使一个人也要用版本控制工具，比如visual SVN
