如何避免找不到文件（WinError 3）？

Question

我试图将我的整个计算机驱动器备份到 google 云存储，人们主要告诉我那是荒谬的，在思考这一切时，我决定只做文档和桌面，我的目标是使用 google 云 SDK，因为我是新手，我喜欢挑战。所以我输入：

gsutil -m rsync -n -J -C -e -r -u -U C:\Users\~~~~\Documents gs://~~~~-pc/documents

当我发送它时，我收到了这条消息：

Caught non-retryable exception while listing file://C:\Users~~~~~\Documents: [WinError 3] The system cannot find the path specified: 'C:\Users\~~~~~\Documents\~~~~~~~~~ Files15 NEGOTIATIONIS05 NEGOTIATIONS FILE - MAIN\Implementation\Temporary Transfers and Permanet Involuntary Force Rearragement\Temporary Transfers and Permanent Involuntary Force Rearrangement FINAL October 3 2014.docx' CommandException: Caught non-retryable exception - aborting rsync

请帮忙！！！

注：“~”为审查

编辑：我进行了调试，但我不知道这是什么意思，这里的输出没有显示我的个人数据：

Answer 1

您的问题是由 MAX_PATH 引起的。默认为 260 个字符。

方法 1 - 指定 UNC 路径

路径前缀为 "\?\"。这会将最大路径名更改为 32,767 个字符。

\?\C:\Users\~~~~\Documents

方法 2 - 更改 Windows 注册表

要解决您的问题，需要编辑注册表以支持最长 32,767 个字符的更长路径名。

更改此注册表项：

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem\LongPathsEnabled
Type: REG_DWORD
Value: 1
