Я пытаюсь выяснить, как удалить все файлы в папке, которые старше двух дней. Дата последнего изменения не помогает. Мне нужно идти по дате в имени файла. Имя файла будет выглядеть примерно так: AD-YYMMDD-B7D или BB-YYMMDD-A6C или RE-YYMMDD-A13T. Это сложно, потому что имя файла не всегда одинаковой длины. Этот сценарий, который я нашел, выглядит так, как будто он поможет, но я не могу понять, как изменить переменные и как задать путь.

REM /D Specifies the pattern being used is based on days.
REM NumberToKeep
REM The number of months (/M) or days (/D) to keep, including the current.
REM For example, entering 1 keeps only the current month/day and 6 would keep the current minus 5.
REM Path The root location to search. Subdirectories will be searched.
REM PatternPrefix
REM The file search pattern placed before of the month/day when building the search string.
REM PatternPostfix
REM The file search pattern placed after of the month/day when building the search string.
REM /L (optional) Lists all files matching the pattern, but does not delete them.
REM /DEL (optional) Deletes all files matching the pattern.

REM Examples:
REM DeleteByDatePattern /M 3 "%WinDir%\system32\LogFiles" ex?? ??.log /DEL
REM Deletes all IIS log files (Windows Server 2003) except for the current and previous two months.

REM Deletes all zip files from the D:\Backup folder except for the current week.
REM The file name pattern assumed above is "*-YYYY-MM-DD.zip"
REM DeleteByDatePattern /M 0 "C:\" *( )* /L
