Upload whole drive to a server using WinSCP in PowerShell skipping all files and folders that cannot be read

I'm trying to copy an entire drive for example D: drive files from a Windows box to a Linux box using PowerShell and WinSCPnet.dll. When I try copying particular folders, I am able to copy all the files from that folder to the Linux path. But when I try to copying the entire D: drive to a Linux box folder, I am getting the following error.

Error retrieving file list for "d:\$RECYCLE.BIN\S-1-5-21-1458064458-1966517317-3155185246-1003*.*". System Error. Code: 5.

$transferOptions = New-Object WinSCP.TransferOptions
$transferOptions.TransferMode = [WinSCP.TransferMode]::Binary
$transferResult = $session.PutFiles("d:\*", "/tmp/some/", $False, $transferOptions)
# Throw on any error
$transferResult.Check()

Expected result should be that it should copy the entire D drive to the destination Linux box folder, but the above mentioned error is coming.

Solution

You can make WinSCP .NET assembly skip all files and folders that cannot be opened by handling Session.QueryReceived event:

# Continue on any error
$session.add_QueryReceived( { 
    Write-Host "Error: $($_.Message)"
    $_.Continue()
} )
 
$session.PutFiles("d:\*", "/tmp/some/").Check()

Code based on article Recursively download directory tree with custom error handling.

Another option is to explicitly exclude the problematic files and folders from the transfer using TransferOptions.FileMask.
