I am on a corporate VPN. I have access to two remote file shares which have windows mapped paths. I can view both file shares in Windows Explorer. My goal is to copy a 1.8 gb .csv file from one share, to the other. I can copy much smaller files with no problem, simply using windows explorer. However, for files around 300mb or greater, I get an error copying the file. The file appears in the destination file share as the correct size, but reading it into python confirms that not all the csv rows are copied.
I am now attempting to copy the file using Windows 10 PowerShell, to open the door to more control over the copy operation, rather than the GUI copy command executed through the Windows 10 desktop environment. (I am replacing the true path names, with stand-ins for privacy)
When I run: Copy-Item \\sourcePath\aFile.csv \\destinationPath\aFile.csv -Verbose -Force
I get the error
Copy-Item : An unexpected network error occurred.
At line:1 char:1
+ Copy-Item '\\sourcePath\ ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [Copy-Item], IOException
+ FullyQualifiedErrorId : System.IO.IOException,Microsoft.PowerShell.Commands.CopyItemCommand
I am hoping that in powershell there is some way to either make the copy operation more robust to VPN bandwidth/connection stability limitations, or to cut my client computer out of the copy operation, and order the source file share to directly copy the file to the destination machine, without my machine serving as a middle man relay between the two. It is clear from my network traffic that my machine is downloading and then uploading the file while the failing copy operation runs.
Are you looking to replace the same item that's in the remote path?
Copy-Item -path \\sourcePath\aFile.csv -destination \\destinationPath\aFile.csv\ -Verbose -Force
It could very well be creds aren't being passed since youre on a VPN which you would have to double hop.
A solution is to use robocopy to copy the file.
robocopy “\\aSourcePath\\” “\\aDestinationPath\\” “aFileInSourcePath.something” /mt /z
runs until the file is transfered, is robust to VPN disruptions that seem to cause standard Windows Explorer copy/paste to fail.

I'm having trouble moving from command prompt to powershell. Usually I hold the shift key while right clicking, select 'open command prompt here', and use dir /s>filename.txt to get a list of all files in a directory and its subfolders. However, my company just updated our computers and now I can't access the command prompt from the network folder I'm trying to get a directory list of.
When I right click and hold the shift key there is no option to 'open the command prompt' from the folder I'm selecting. I opened command prompt manually and attempted to navigate to the network folder, but no dice. I get an error regarding UNC (?) or that it basically can't do it because it's a network folder.
I attempted to use powershell the same way I use Command prompt given as an answer Here, however I get an error message
PS Microsoft.PowerShell.Core\FileSystem::\\my.company.com\companydata\MainProject\Records\Field Work\Invoices> dir /s >file.txt
dir : Cannot find path 's' because it does not exist.

+ dir /s >file.txt
+ ~~~~~~~~~~~~~~~~
+ CategoryInfo : ObjectNotFound: (s:String) [Get-ChildItem], ItemNotFoundException
+ FullyQualifiedErrorId : PathNotFound,Microsoft.PowerShell.Commands.GetChildItemCommand
I also attempted to re-instate the command prompt option in the expanded right-click +shift key list as detailed here. However, I don't have the permissions required to run all the steps.
I just need a directory of everything in a specified network folder, just a list of all the files in the folder and subfolders: file paths, file names, and dates created. I used to be able to get it using command prompt but apparently, that's not available. I'm unsure how to use powershell, and help is much appreciated, in either getting new, simple, easy to understand powershell resources so I can teach myself, or in finding a work around so I can continue using command prompt.
Is there an interpretation guide I can use that goes from Command Prompt to Powershell, and also will let me list files in network drives? (I can sort of understand the current resources out there for having powershell list files in a directory on the computer, but what I need is the powershell to be able to list files in a specified network folder).
In powershell, dir is an alias for Get-ChildItem I believe you're getting that error because switches/arguments work differently in PowerShell. The first parameter by position is Path, so the system thinks you are providing the value /s for the path.
You can do this in PowerShell without having to launch cmd by leveraging Get-ChildItem. As you what the complete structure including the subfolders, user -Recurse
You could also export to csv instead of text file. There's a lot of data - Select can be used to restrict which fields you export.
$Path = "\\my.company.com\companydata\MainProject\Records\Field Work\Invoices"
$Files = Get-ChildItem -Path $Path -Recurse
$Files | Out-file file.txt
$Files | Select-Object FullName,CreationTime | Export-Csv file.csv -NoTypeInformation
I am working from Windows Server 2012 R2 from that server I am connected to a internal network, to which there are numerous computers that I have access to.
What I want to do is based on a specific users IP address in that network I want to pull 3 specific files out of that computer and make a copy to a specified location on my server. The files are always located in the same file path location for each individual computer and have the same file name.
From what I understand is that I should be able to write a script to perform this.
Copy-Item -ComputerName -Path filepath -Destination filepath destination
I don't want to use the computer name as it is more convoluted to find, it would be nice to enter in the IP of the address I am pulling the 3 files from.
Or if there is an easier-quicker way to copy the files from the PowerShell environment that would also be very helpful.
If you want to copy files from a remove machine to e.g. your own, you could run
Copy-Item -Path '\\<ip>\<file>' -Destination <local path>
E.g. I tried running
Copy-Item -Path '\\10.0.0.10\C$\winbox.exe' -Destination c:\tmp
between two domain joined computers, to which my user account has access to, works fine. 10.0.0.10 is the remote machine.
I am trying to deploy windows 10 app that I created to a laptop. In my computer everything goes fine, but in the laptop the Add-appPackage first recognizes the relevant package files, but when running the line in the script that makes the unbundle it fails and returns with:
' The system cannot find the file specified' eventhough the files exists.
I tried to make a deploy using the -register flag from working solution directory but the result was the same.
I use in my computer Windows 10 HOME and the Laptop is Windows 10 Pro but I think it does not matter.
The line in the script file generated by the visual studio packager which fails is:
Add-AppxPackage -Path $DeveloperPackagePath.FullName -DependencyPath $DependencyPackages.FullName -ForceApplicationShutdown
I checked the variables - they contain correct data.
Afterwards it outputs the error with the line:
$Error[0] # Dump details about the last error
that does not give me too much details about which file is missing as you can see in the full output:

I tried also getting information with get-AppxLog but it does log the error.
What happens? What is missing? Is there a way to get more information about the error?
Where does Windows 10 put the appx? Is there a way to make a bypass and take the files from an existing executable version, something like .exe files and copy them as is to the laptop?
My script uses the Powershell splitpipeline module, to bring parallel process and queues features.
The script and the module are stored on shared server, like \server\c$ , the idea is be able to run it from any computer.
Tried to put at begining of the script import-module \\server\c$\SplitPipeline but I recieve the error:
import-module : Could not load file or assembly 'file://\\server\c$\SplitPipeline\SplitPipeline.dll' or one of its dependencies.
Operation is not supported. (Exception from HRESULT: 0x80131515)

If I try to copy it from the srv to the pc with:
Copy-Item -Path \\server\c$\SplitPipeline -Destination C:\windows\system32\WindowsPowerShell\v1.0\Modules -recurse -force
I get a access denied
any ideas¿?
thanks
The issue you're experiencing is that .NET assemblies can't be loaded from an untrusted UNC path, without special configuration. As you already discovered, the simplest solution is to copy the module to your local computer first.
To work around the "Access Denied" message, copy the module to your user directory, not the system-wide directory.
c:\users\<username>\Documents\WindowsPowerShell\Modules
You need to run PowerShell "as Administrator" in order to have permission to copy to the system folder, however it is generally recommended not to modify the default system directory. Instead, copy the module to your user folder (as above).
I have the need to run a Powershell command on a remote computer that will move a file from the remote computer to another computer on the network.
PS H:\> invoke-command -computername server1 -scriptblock {move-item c:\jobs\archive\A1051626.zip "
\\FilerServer\jobs\archive\"}
This command results in the following error:
Access to the path is denied.
+ CategoryInfo : PermissionDenied: (C:\jobs\archive\A1051626.zip:FileInfo) [Move-Item], Unauthorized
AccessException
+ FullyQualifiedErrorId : MoveFileInfoItemUnauthorizedAccessError,Microsoft.PowerShell.Commands.MoveItemCommand
If I edit the PS command to copy the file to a local system folder the command runs fine.
The user account that I am running the PS script from on my local computer has permissions to copy files to the remote file server. I have double checked this, and I can mannually copy the files to the file share from Windows Explorer.
What is preventing the copy operation in PowerShell? How can I get this task to run?
Thanks!
It is probably a double hop issue. You have to use CredSSP to delegate your credentials to the remote computer.
Try the solution mentioned here: http://blogs.msdn.com/b/clustering/archive/2009/06/25/9803001.aspx
Also, note that Move-Item may not work for moving from filesystem to network share. You might have to use Copy-Item and Remove-Item
