Copy-Item in PowerShell; The given path's format is not supported
提问by ajnatural
I'm relatively new to PowerShell, and I was trying to copy files using a text file formatted like this:
我对 PowerShell 比较陌生，我试图使用格式如下的文本文件复制文件：
file1.pdf
dir1\dir2\dir3\dir 4
file2.pdf
dir1\dir5\dir7\di r8
file3.pdf
...etc.
Where the first line of each entry is a file name, and the second is the file path from C:\Users. For example, the full path to the first entry in the file would be:
其中每个条目的第一行是文件名，第二行是来自 C:\Users 的文件路径。例如，文件中第一个条目的完整路径为：
C:\Users\dir1\dir2\dir3\dir 4\file1.pdf
The code below is what I currently have but I'm getting the error: 'The given path's format is not supported.' and another error after that telling me it can't find the path, which I assume a result of the first error. I've played around with it a bit, and I'm getting the impression that it's something to do with passing a string to Copy-Item.
下面的代码是我目前拥有的代码，但出现错误：“不支持给定路径的格式。” 之后的另一个错误告诉我它找不到路径，我认为这是第一个错误的结果。我玩过它一点，我得到的印象是它与将字符串传递给 Copy-Item 有关。
$file = Get-Content C:\Users\AJ\Desktop\gdocs.txt
for ($i = 0; $i -le $file.length - 1; $i+=3)
{
$copyCommand = "C:\Users\" + $file[$i+1] + "\" + $file[$i]
$copyCommand = $copyCommand + " C:\Users\AJ\Desktop\gdocs\"
$copyCommand
Copy-Item $copyCommand
}

You can read the file in chunks of three lines, join the first two elements to form a path and use copy-item to copy the files.
您可以分三行读取文件，将前两个元素连接起来形成路径，然后使用 copy-item 复制文件。
$to = "C:\Users\AJ\Desktop\gdocs\"
Get-Content C:\Users\AJ\Desktop\gdocs.txt -ReadCount 3 | foreach-object{
$from = "C:\Users\" + (join-path $_[1] $_[0] )
Copy-Item -Path $from -Destination $to
}

Try this (inside the cycle):
试试这个（在循环内）：
$from = "C:\Users\" + $file[$i+1] + "\" + $file[$i]
$to = "C:\Users\AJ\Desktop\gdocs\"
Copy-Item $from $to
$fromand $toare arguments for Copy-Itemcmdlet. They are bound to parameters -Pathand -Destinattion. You can check this via this code:
$from和$to是Copy-Itemcmdlet 的参数。它们绑定到参数-Path和-Destination。您可以通过以下代码进行检查：
Trace-Command -pshost -name parameterbinding {
Copy-Item $from $to
}
