删除早于X天的文件..但不是按修改日期

Question

我有一个.exe我的工作场所的配置文件，你可以指定删除文件（特别是在我的测试中保留最后说的30天文件[日志和sql很好]），它甚至清除子文件夹。但是它按修改日期删除，因此带有一些旧数据的较新文件夹会删除旧的remnents。

Folder1:
File:   Modified:
File 1  2018/02/02
File 2  2010/05/06
File 3  2018/02/01

Folder 2:
File:   Modified:
File 1  2011/12/30
File 2  2006/01/16     
File 3  2018/02/02

会离开：

Folder1:
File:   Modified:
File 1  2018/02/02
File 3  2018/02/01

Folder 2:
File:   Modified:    
File 3  2018/02/02

有没有改变这个，所以它保留了最后30个文件夹和内容，删除其他一切？

这是我所拥有的“cleaner”.exe.config文件的内容：

<?xml version="2.0" encoding="utf-8"?>  <configuration>    <configSections>    </configSections>    <!-- Make sure that every new location has a name with an increasing number e.g clear 1 -->   
    <appSettings>
            <add key="connstring" value="Data Source=localhost;user id = *****;password = *****;Initial Catalog =Database;" />
            <add key="sqldays" value="180" />
            <add key="LogLocation" value="C:\File\Logs\Cleaner\" />
            <add key="clear" value="C:\Directory\Logs,90" />
            <add key="clear2" value="C:\Directory\CSV\Backup,30 " />
            <add key="fileExtensions" value=".txt,.csv,.log,.fmt,.hdr,.Log" />

            <add key="ClientSettingsProvider.ServiceUri" value="" />   </appSettings> </configuration>

只是为了关闭它，它对修改日期无关紧要，文件只需要“消失”所以我在配置文件中添加了几个目录并让它松散。

例：

<?xml version="2.0" encoding="utf-8"?>  <configuration>    <configSections>    </configSections>    <!-- Make sure that every new location has a name with an increasing number e.g clear 1 -->   
    <appSettings>
            <add key="connstring" value="Data Source=localhost;user id = *****;password = *****;Initial Catalog =Database;" />
            <add key="sqldays" value="180" />
            <add key="LogLocation" value="C:\File\Logs\Cleaner\" />
            <add key="clear" value="C:\Directory\Logs,90" />
            <add key="clear2" value="C:\Directory\CSV\Backup,30 " />
            <add key="clear3"value="C:\Directory1\CSV\Backup,30 " /> 
            <add key="clear4" value="C:\Directory2\CSV\Backup,30 " />
            <add key="fileExtensions" value=".txt,.csv,.log,.fmt,.hdr,.Log" />

            <add key="ClientSettingsProvider.ServiceUri" value="" />   </appSettings> </configuration>
