Question

在这里的另一位成员的帮助下，我能够创建两个脚本：一个使用工作流将PDF转换为XPS，另一个将XPS转换为PDF。将它们组合到一个脚本中时，第一个工作流将文件转换为XPS，但是，第二个工作流似乎无法在适当的时间工作或根本不工作。在第二个工作流程的末尾有一些清理项目似乎正常工作。我可以在适当的时间以某种方式延迟第二个工作流的开始吗？提前致谢！另一个问题可以在Print PDF to XPS using Powershell找到。

# Define the directories used for converting files

$xps_dir = "aaa"

$xps_archive = "ddd"
$unsecure_pdf_archive = "eee"

$date = $(get-date -f yyyy-MMM-dd)


# Archives old files except secure pdfs
