SynchronizeDirectories returns empty collection in SynchronizationResult.Removals

First, thanks for your software! :)

I am using SynchronizeDirectories to sync local files to Ubuntu server, and vica versa using SFTP Protocol. When syncing to SFTP server, the SynchronizationResult.Removals have list of removed files. When syncing from SFTP server to local, the Removals are empty list.

I have reduced this to very simple test case. One side has an empty folder, other - one file. I have enabled logging, and also capturing .xml file by placing break-point at XML file deleting in Session.cs file:
Logger.WriteLine("Deleting XML log file [{0}]", XmlLogPath);
try
{
    File.Delete(XmlLogPath);
}

When syncing from local to SFTP, the XML file looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<session xmlns="http://winscp.net/schema/session/1.0" name="MY_SERVER_NAME" start="2019-07-18T13:36:17.488Z">
  <group name="sftp://ubuntu@MY_SERVER_NAME:22 -hostkey=&quot;ssh-rsa 2048 *************************=&quot; -privatekey=&quot;C:\key.ppk&quot; -timeout=60 -passphrase=***" start="2019-07-18T13:36:20.219Z">
  </group>
  <group name="" start="2019-07-18T13:36:21.029Z">
    <cwd>
      <cwd value="/home/ubuntu" />
      <result success="true" />
    </cwd>
  </group>
  <group name="remote -delete  -nopermissions -preservetime -transfer=&quot;binary&quot; -resumesupport=&quot;off&quot; -criteria=&quot;either&quot;  -- &quot;c:\test case\&quot; &quot;/home/ubuntu/the test directory/&quot;" start="2019-07-18T13:36:21.108Z">
    <rm>
      <filename value="/home/ubuntu/the test directory/first file.txt" />
      <result success="true" />
    </rm>
  </group>
  <group name="" start="2019-07-18T13:36:21.942Z">
  </group>
</session>

There is entry rm in the XML file, and SynchronizationResult.Removals have one entry. So far so good. Now I try sync in other direction. Capturing XML file:
<?xml version="1.0" encoding="UTF-8"?>
<session xmlns="http://winscp.net/schema/session/1.0" name="ubuntu@MY_SERVER_NAME" start="2019-07-18T13:06:40.914Z">
  <group name="sftp://ubuntu@MY_SERVER_NAME:22 -hostkey=&quot;ssh-rsa 2048 *************************=&quot; -privatekey=&quot;C:\some_key.ppk&quot; -timeout=60 -passphrase=***" start="2019-07-18T13:06:43.509Z">
  </group>
  <group name="" start="2019-07-18T13:06:43.611Z">
    <cwd>
      <cwd value="/home/ubuntu" />
      <result success="true" />
    </cwd>
  </group>
  <group name="local -delete  -nopermissions -preservetime -transfer=&quot;binary&quot; -resumesupport=&quot;off&quot; -criteria=&quot;either&quot;  -- &quot;c:\test case\&quot; &quot;/home/ubuntu/the test directory/&quot;" start="2019-07-18T13:06:43.692Z">
  </group>
  <group name="" start="2019-07-18T13:06:44.555Z">
  </group>
</session>

There is no entry for rm, and Removals are also empty. However, the file is synced correctly (deleted), and other log file also have clue that file was deleted:

Am I doing something wrong? If you need more information, I will gladly provide it.

Thanks in advance! :)

Re: SynchronizeDirectories returns empty collection in SynchronizationResult.Removals

As the documentated, the SynchronizationResult.Removals is "Collection of remote file removals".
https://winscp.net/eng/docs/library_synchronizationresult#removals
Local file removals are not returned currently.

See this example how to find list of removed files yourself (it's in PowerShell though):
https://winscp.net/eng/docs/library_example_keep_local_directory_up_to_date
(see the "scan for removed local files" section of the code)
