Filemask not Working on Folders

Hello Guys,

Im using WinSCP with PowerShell-script to download a couple of folders with files in it.
So FTP looks like this:
/remotepath/folder1/file1.xml
/remotepath/folder1/file1.pdf
/remotepath/folder2/file2.xml
/remotepath/folder2/file2.pdf
... and so on

Im running the command twice. First run to download the complete folders including the files. The second run with filemask and "true" parameter, to only delete the files in the remote folders. And don't know any better way but I think it should work...

The second run is the one not working fine, as it tries to delete the folders (what's not allowed per accessrights) and then the script breaks after the first folder.

My Filter is this: -filemask="*.xml,*.pdf"
The filter itself is working fine, it deltes xml or pdfs and ignores other files

My Script is just like this:
# Load WinSCP .NET assembly
Add-Type -Path "D:\Script\WinSCPnet.dll"
 
# Setup session options
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Sftp
    HostName = "server"
    UserName = "user"
    Password = "pass"
    SshHostKeyFingerprint = "ssh-rsa 2048 lalalala"
}
 
$session = New-Object WinSCP.Session
$session2 = New-Object WinSCP.Session
$session2.SessionLogPath = "D:\Script\log\sessionlog.txt"
 
 
# Connect
$session.Open($sessionOptions)
$session2.Open($sessionOptions)
 
#Transfer Options
$transferOptions = New-Object WinSCP.TransferOptions
$transferOptions.TransferMode = [WinSCP.TransferMode]::Binary
 
# Download files    
$session.GetFiles("/remotePath/*", "D:\localPath\", $False, $transferOptions)
 
#Transfer Options2
$transferOptions2 = New-Object WinSCP.TransferOptions
$transferOptions2.TransferMode = [WinSCP.TransferMode]::Binary
$transferOptions2.FileMask = "*.xml,*.pdf"
 
# Delete *.xml   
$session2.GetFiles("/remotePath/*", "D:\localPath\", $True, $transferOptions2)
As you can see from the log, it tries to delete the folders as well:

I would be fine with two solutions, either the filemask starts working fine and ignores the folders or the script just continues on errors.

Thanks alot

Btw, your script should not fail on any errors, as you are not checking for errors at all. Are you sure the logs comes from the code you have posted?
Yes, I am sure and it fails because I'm not allowed to delete the folder. I found something else out.
If you have different types of files in the subfolder, lets say .xml and .pdf and you use the file filter for .xml ($transferOptions.FileMask = "*.xml"), it's processing all the folders cause in every folder, there is at least one file left with the extension .pdf.
It only crashes when you delete the last file in a folder, then (for some reason), it tries to delete the subfolder as well and is not caring about the FileMask.

First, if you want to remove files, use Session.RemoveFile. That's the only correct solution.
To be honest, I have no idea how to do this. I would have to enumerate all files in all subfolders or at least all subfolders on the server. Do you have a peace of code as an example?
Thanks alot

Sorry, I'm lost. If you want me to investigate this, please post the code and session log file.

The Session.GetFiles returns list of all transferred files in TransferOperationResult.Transfers. Just iterate it, and call Session.RemoveFile for each transferred files.

Btw, note that this all makes sense only, if you goal is to delete the files only after all files are transferred. If you are ok with deleting the files as they are transferred, just use Session.GetFiles with remove = false straight away.

I think you mean remove = true. That's not working because it tries to delete the folder as well after deleting the last file in the folder even when using file filter.

Im using this solution with PowerShell and it works perfectly:
#Enum Files
$RemoteFilesPDF = $session.EnumerateRemoteFiles("/remotePath/", "*.pdf", [WinSCP.EnumerationOptions]::AllDirectories)
$RemoteFilesXML = $session.EnumerateRemoteFiles("/remotePath/", "*.xml", [WinSCP.EnumerationOptions]::AllDirectories)
   
# PDF delete
foreach ($fileToDelete in $RemoteFilesPDF)
{
    $session.RemoveFile($fileToDelete.FullName)
} # end foreach
        
# XML delete
foreach ($fileToDelete2 in $RemoteFilesXML)
{
    $session.RemoveFile($fileToDelete2.FullName)
} # end foreach
Many thanks for your help and patience!

Re: Filemask not Working on Folders

Your code "works". But it is inefficient and it is not transactionally safe. You enumerate remote folder three times. And if new file is added to the remote folders between GetFiles and EnumerateRemoteFiles, you may delete a file that was not downloaded. At the very least, do EnumerateRemoteFiles before GetFiles. Though once you already enumerate files, instead of separate GetFiles and RemoveFile do GetFileToDirectory with remove = true:
foreach ($file in $RemoteFilesPDF)
{
    $session.GetFileToDirectory($fileToDelete.FullName, "D:\localPath", $True)
} # end foreach

Re: Filemask not Working on Folders

Yes, I enumerate the files before downloading and I check the Download for errors first. But your code is a very good idea. I just don't know if this creates the subfolders before copying the files. I'm gonna test this the next days. Thanks

Re: Filemask not Working on Folders

If there are subfolders, then the code needs to be more complicated.

But then it is still better to do what I have suggested originally:
$result = $session.GetFiles("/remotePath/*", "D:\localPath\")
$result.Check()
 
foreach ($transfer in $result.Transfers)
{
    # Not sure if this condition is needed
    if ($transfer.FileName.EndsWith(".jpg") -or
        $transfer.FileName.EndsWith(".pdf"))
    {
        $session.RemoveFile($transfer.FileName)
    }
}
