バッチは古い形式で、PowerShellと比べて非常に複雑ですが、バッチを使用して多くの古いWindowsマシンと互換性があることを確認する必要があります。ディレクトリ作成日をBATCHの変数に出力する
私は、バックアップドライブ上のストレージ可用性がコンピュータドライブ上のデータを保持するのに十分であることを確認するバックアップスクリプトを作成しています。
スペースが不足している場合は、最初に見つかったバックアップと作成日を見つけておき、次の日付を削除してバックアップが実行可能かどうかを確認する必要があります。
私が抱えている問題は、最も古い日付のディレクトリを見つけて変数に入れてから、次に古いディレクトリを見つけてそれを削除し、再度領域を確認することです。
これは、私は、スクリプトの検証のために持っているものです。

私は、ディレクトリの日付を取得するために多くのことを利用してきた、そしてそれはバッチのために「不可能」と思われます。私は仕事のためにこれを行う必要があり、数日間それに固執しています。 助けてくれてありがとう！
EDIT： スティーブンが答えてくれてありがとう、それはまさに私が探していたものでした。 完成したコードが何であるか不思議だったあなたのために、私はここに投稿します！助けてくれてありがとう。

::xCopy for data transfer of all user information to an external drive.
::Created by Benjamin Chaney
::Version notes-
::V1.0 - Initial release
::V1.1 - Replaced XCOPY commands with updated ROBOCOPY commands
::V1.2 - Created script to verify date and create a directory of todays date
:: in YYYY_MM_DD format on backup drive.
:: Also created checks for administrative rights, outlook being opened
:: and if the backup drive is plugged in.
::V1.3 - Fixed bugs where it would give an error giving an invalid destination
::V1.4 - Enhanced the ROBOCOPY command to be more efficient
::V1.5 - Created an audio queue when backup is finished.
::V1.6 - Script checks for if there is enough disk space on the drive before the backup
::V1.7 - Updated to remove second oldest directory in backup drive if no space is available
