【问题描述】：

当我使用 adb pull 从手机中提取一些文件时，出现如下错误：无法创建“某些文件”：没有这样的文件或目录

The detail is: I create a file named "a.txt", under folder /mnt/sdcard/DCIM/100ANDRO/vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv, the "v....v" is a folder I create under /mnt/sdcard /dcim/100ANDRO/, then I open command terminal and switch to C:/ and run the command : C:\aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa>adb pull /mnt/sdcard/DCIM/100ANDRO/vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv folderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolder

这里：a........a 是我在 C:\ 磁盘中创建的文件夹，v....v 是我在 /mnt/sdcard/dcim/100ANDRO/ 下创建的文件夹，“文件夹...文件夹...文件夹”是我要创建的目标文件夹。

结果是：pull:构建文件列表...

pull: /mnt/sdcard/DCIM/100ANDRO/vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv/a.txt -> folderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolder/a.txt
cannot create 'folderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolderfolderf
olderfolderfolderfolderfolderfolder\a.txt': No such file or directory

但如果目标文件夹长度较短，则命令成功！

C:\aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
aaaaaaaaaaaaaaaaaaaaaaaaaaa>adb pull /mnt/sdcard/DCIM/100ANDRO/vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv

pull: building file list...

为什么会这样？它是 adb.exe 的缺陷吗？请帮忙，非常感谢。

【问题讨论】：

这是因为文件名太长了吗？

【解决方案1】：

查看以下链接： http://msdn.microsoft.com/en-us/library/aa365247.aspx

在 Windows API 中（以下段落讨论的一些例外情况），路径的最大长度为 MAX_PATH，定义为 260 个字符。

你的路径是否穿越 260/？

【讨论】：

谢谢你的回答，它有帮助。但是如何在 Windows 的 Python 中使用长路径？

【解决方案2】：

我在使用 cmd.exe + 260 字符组策略编辑器/注册表修复 + 重启时遇到了这个问题。切换到 powershell 后，我就可以通过手机 adb pull 我的文件了。如果这不起作用，请尝试 git bash。
