'源和目标路径必须具有相同的根。移动不会跨卷运行 [英] 'Source and destination path must have identical roots. Move will not work across volumes

问题描述

我想将所有.emb文件从pendrive（驱动器i :)移动到名为To（C：\ To）的文件夹。我在EmbFile中获取所有.emb文件，但是当我想要移动这些文件时，我收到错误（'源和目标路径必须具有相同的根。移动将无法跨卷工作）尝试了很多但没有得到解决。任何人都可以帮助我。



i我在下面提到了我的代码。



什么我试过了：



Imports System.IO



Public Class FRM_Main



私有子FRM_Main_Load（发件人为对象，e为EventArgs）处理MyBase.Load



Dim Copy_From As String = 我：

Dim Copy_To As String =C：\ To



尝试

昏暗EmbFiles = Directory.EnumerateFiles（Copy_From，*。Emb，SearchOption.AllDirectories）



每个currentFile作为字符串在EmbFiles中

Dim fileName = currentFile.Substring（Copy_From.Length + 1）

Directory.Move（Path.Combine（currentFile，fileName），Path.Combine（Copy_To，fileName））

下一页

赶上Ex Exception

Console.WriteLine（Ex.Message）

结束尝试



结束子



结束类

i have mentioned my code below.

What I have tried:

Private Sub FRM_Main_Load(sender As Object, e As EventArgs) Handles MyBase.Load

Dim Copy_From As String = "I:"
Dim Copy_To As String = "C:\To"

Try
Dim EmbFiles = Directory.EnumerateFiles(Copy_From, "*.Emb", SearchOption.AllDirectories)

For Each currentFile As String In EmbFiles
Dim fileName = currentFile.Substring(Copy_From.Length + 1)
Directory.Move(Path.Combine(currentFile, fileName), Path.Combine(Copy_To, fileName))
Next
Catch Ex As Exception
Console.WriteLine(Ex.Message)
End Try

End Sub

End Class

不，这是不可能的。移动是一项特殊操作，只能在同一个硬盘上工作。

基本上移动是复制+删除的特殊情况。

标准操作是

No, it is impossible. Move is a special operation that can only work on same hdd.
Basically a move is a special case of copy+delete.
The standard operation is

copy source to target
delete source

当源和目标在相同的卷上时，技术技巧允许如果没有文件的真实副本，那就是移动。

it happen that when source and target are on same volume, a technical trick allow you to do it without a real copy of the files, that is the move.
