This will delete all files in a backup directory older than 3 days:

<file>
forfiles -p z:\backup -s -m *.* -d -3 -c "cmd /c del /q @path"
</file>

To test it first, this will print out each file that you will be deleting:

<file>
forfiles -p z:\backup -s -m *.* -d -3 -c "cmd /C Echo 0x22@Path\@File0x22"
</file>

Syntax for Windows 2008:

<file>
forfiles /P "C:\Mysql_backup" /S /M *.sql /D -30 /C "cmd /c del @PATH"
</file>
