Question

我希望能够列出shell中的文件：python脚本中的appsfolder，但需要完整的路径才能使用os.list执行此操作。有没有办法获得完整的路径（或有人知道它）？或者，我可以用不同的方式列出这些文件吗？我可以＆＃34; cd＆＃34;对吗？

该脚本背后的想法是自动创建所有Windows应用商店应用的快捷方式（通过他们拥有＆＃34;长名称＆＃34;我认为的属性来识别）并将这些快捷方式提取到文件夹中程序Launchy可以检测到它们。我不想每次下载或删除应用程序时都必须手动完成创建快捷方式（并重命名以删除＆＃34; - 快捷方式）的过程，所以我想我自动完成它

这是一个功能，希望能够为“应用程序”虚拟文件夹（即FOLDERID_AppsFolder）中列出的Windows应用商店应用创建快捷方式。要对Windows应用商店应用进行分类，它会在应用用户模型ID中查找感叹号，因为AUMID的格式应为“PackageFamily！ApplicationID”（请参阅Automate Launching UWP Apps）。为了可靠性，它将每个软件包系列与用户注册的软件包系列进行交叉检查。

示例

if __name__ == '__main__': desktop = shell.SHGetFolderPath(0, shellcon.CSIDL_DESKTOP, 0, 0) target_dir = os.path.join(desktop, 'Windows Store Apps') if not os.path.exists(target_dir): os.mkdir(target_dir) update_app_shortcuts(target_dir)

有没有办法获得shell的完整路径：Windows 10上的appsfolder？
