推荐答案

我在 Windows 10 上遇到了类似的问题:有时我的 python 脚本无法重命名目录，即使我可以毫无问题地手动重命名它.

I had a similar problem on Windows 10: sometimes my python script could not rename a directory even though I could manually rename it without a problem.

我使用 Sysinternal 的 handle.exe 工具发现 explorer.exe 有一个指向我试图重命名的目录的子目录的句柄.事实证明，资源管理器将此子目录添加到其快速访问"部分，这阻止了我的脚本重命名文件夹.

I used Sysinternal's handle.exe tool to find that explorer.exe had a handle to a sub-directory of the directory I was trying to rename. It turns out explorer was adding this sub-directory to its "Quick Access" section which prevented my script from renaming the folder.

我最终从资源管理器 -> 查看 -> 选项 -> 常规 -> 隐私中禁用了在快速访问中显示常用文件夹"选项.

I wound up disabling the "Show frequently used folders in Quick access" option from Explorer -> View -> Options -> General -> Privacy.
