尝试使用 powershell 复制我的文档文件夹

Question

$dir = Read-Host 'Please enter the letter drive to backup user folder.'
copy-item ($env:USERPROFILE+"\Documents") -destination ($dir+":\Backup")   -recurse

I"m trying to copy my documents folder, however when I look in the backup folder I see that it copies my pictures and my videos as well. In addition to that I get the following errors:

Copy-Item : Access to the path 'C:\Users\admin\Documents\My Music' is denied.
At C:\Users\admin\Desktop\Untitled1.ps1:2 char:10
+ copy-item <<<<  ($env:USERPROFILE+"\Documents") -destination ($dir+":\Backup") -recurse
+ CategoryInfo          : PermissionDenied: (My Music:DirectoryInfo) [Copy-Item], UnauthorizedAccessException
+ FullyQualifiedErrorId : CopyDirectoryInfoItemUnauthorizedAccessError,Microsoft.PowerShell.Commands.CopyItemCommand

Copy-Item : Access to the path 'C:\Users\admin\Documents\My Pictures' is denied.

+ CategoryInfo          : PermissionDenied: (My Pictures:DirectoryInfo) [Copy-Item], UnauthorizedAccessException

Copy-Item : Access to the path 'C:\Users\admin\Documents\My Videos' is denied.

+ CategoryInfo          : PermissionDenied: (My Videos:DirectoryInfo) [Copy-Item], UnauthorizedAccessException
+ FullyQualifiedErrorId : CopyDirectoryInfoItemUnauthorizedAccessError,Microsoft.PowerShell.Commands.CopyItemCommand

It also makes a user folder in the root of the selected drive.

This may work better for you. You currently might be parsing sym links rather than getting the actual path. Using this method will get the actual folder path every time.

$dir = Read-Host 'Please enter the letter drive to backup user folder.'
copy-item -Path [environment]::getfolderpath('mydocuments') -destination ($dir+":\Backup") -Recurse
