>             Project: Log4net
>          Issue Type: Bug
>          Components: Appenders
>    Affects Versions: 2.0.8
>            Reporter: EbenZhang
>
> Those three don't work well together, the oldest file won't be deleted, e.g.
> {code:xml}
> <appender name="MyAppender" type="log4net.Appender.RollingFileAppender">
>       <file type="log4net.Util.PatternString" value="SomeFolder\myLog.txt" />
>       <appendToFile value="true" />
>       <rollingStyle value="size" />
>       <maximumFileSize value="2KB"/>
>       <maxSizeRollBackups value="10"/>
>       <countDirection value="1"/>
>       <preserveLogFileNameExtension value="true"/>
>       <staticLogFileName value="false" />
> </appender>
> {code}
> Because in [RollingFileAppender line 
> 1496|https://github.com/Nicologies/logging-log4net/blob/develop/src/Appender/RollingFileAppender.cs#L1496],
>  the folder will be stripped, as a result the code is unable to find the file 
> to delete.
> {code:java}
> string extension = Path.GetExtension(archiveFileBaseName);
> string baseName = Path.GetFileNameWithoutExtension(archiveFileBaseName);
> int lastDotIndex = baseName.LastIndexOf(".");
> if (lastDotIndex >= 0)
> {
>     archiveFileBaseName = baseName.Substring(0, lastDotIndex) + extension;
> }
> {code}
