[英]Python - Get Path of Selected File in Current Windows Explorer
這需要大量的黑客攻擊,但粗略的解決方案如下:

所以這樣做是不斷檢查活動窗口是否屬於資源管理器窗口使用的類,然后遍歷子小部件以查找地址欄和文件列表視圖。 然后它從列表視圖中提取文件列表並請求選定的索引。 它還從地址欄中獲取和解碼文本。
在底部,信息然后組合在一起,為您提供完整路徑、文件夾路徑、文件名或它們的任意組合。
我已經用 python3.4 在 windows xp 上測試過這個,但是你需要安裝 win32gui 和 win32 conn 包。
如果您想要 Windows Vista 或更高版本(不確定 Vista),請在此處查看我的答案: https : //stackoverflow.com/a/52959617/8228163 。 我將修正后的 James Kent 的答案與較新的 Windows 和 Olav 的答案(在該線程上)混合在一起,然后將其與較新的 Windows 一起使用並僅選擇活動窗口。 我也解釋了如何讓它從所有 Windows 資源管理器窗口中獲取文件(奧拉夫自己說的,我只是在我的回答中再次解釋了)。 對於 XP,只需將原始 James Kent 的答案與 Olav 的答案混合即可。 我也在我的回答中更好地解釋了這一點。
可能 OP 不再需要這個了,但也許其他人會需要它 - 我需要它但沒有完整的答案,所以這可能對某人有所幫助。
感謝 Olav 和 James Kent 的答案,因為我會花更多的時間來嘗試找出如何做到這一點(我是 Python/任何語言的初學者 - 只編碼一年,所以它會花費很多時間,也許我必須將它與另一種語言混合)。 再次感謝 OP,感謝他們提出問題並讓合適的人在合適的時間回答! (因為 Olav 在鏈接上引用的來源不再存在)。
希望這有幫助! 干杯!
# Import Statement. import subprocess # Trigger subprocess. subprocess.popen(r'explorer /select,"C:\\path\\of\\folder\\file"'
抱歉,您嘗試實現的目標沒有多大意義,因為您可以擁有多個資源管理器窗口,其中選擇了文件,多個顯示器,甚至在同一台機器上運行的多個終端會話。
