[文件操作] [分享]批处理版undel实现数据安全删除、恢复

bat_fan

简单说明:undelete命令能恢复del命令删除了的文件

不足之处:对个人隐私、机密信息有不小隐患。(Microsoft处于安全考虑，这类“高危”命令几乎都精简掉了。)

优点 :undo、后悔药之功效。


吹捧的话就不说了，简言之，小巧易用。

已测试系统：Win 7 旗舰7600 + Windows XP Mode

包组成：mydel.bat、undel.bat、mdel.bat(欢迎自行转换成其他格式，如exe）
mydel.bat：删除一(多)个文件，慎用通配符[只能匹配第一个，如果存在]。
undel.bat：恢复用mydel命令删除的文件，不支持引号。
mdel.bat：mydel.bat的封装，实现带通配符的某一特征的文件类删除。(mode_del之意)

且看代码

实际就是用文件夹来代替类似回收站的功能，对吧。
