Was synchronizing a folder from my local windows host to a linux host. I browsed to a different local directory than originally selected, selected the remote target direction, and then clicked start in a new window. That is when this error occurred.

<Hello,
I started synchronization between two directories (there is 99 directories and each one contain others 99 subdirectories which contain the target files). The comparison was successful. Against default I chacked also Size File, but after confirmation of the transfer (after some time) this error popped up. Folders are - Source is linux, target is Windows - both on local Network>

<Try to describe precise steps that lead to the problem (where do you click, what keys do you press, what do you see, etc.)> Had viewed a preview checklist created by the Synchronize option, which I was using for the first time. I decided to uncheck all the files with a red 'X, as these had been recently added separately to the target server. Then when I clicked on the OK, the error shown below came up and the preview checklist disappeared. It had taken WinSCP 36 hours to finish this initial synch between the source and remote target servers, as there were around one million files to access on the source server. Before doing the synch, I'd done a copy of the files from the I drive on the source to the I drive on the target server using the same preferences and same group of folders many times. There were only 2,200 red 'X' files, with about 1,300 green arrow files (~1.2 GB) and a few dozen red arrow files (~330MB) in the preview list. Both servers are Windows 2019 VMs with the latest updates to them, plenty of space on their drives, no issues with their cpus, amount of memory or network connectivity and the files being synched were from 2015 to the present. Event Viewer is fine.
<If relevant, consider attaching a session log file or a screenshot)> Well, since the sync list disappeared, I've not got a useful screenshot or session log file to attach.

I was doing a sync of two network folders. I set it to run, then left the computer alone for a few hours while I finished getting ready for work and headed into the office. I'm working on it remotely, so I didn't see the error until I reconnected to check the status of the sync. Unfortunately, I didn't have logging enabled, so there is no file to attach.

Hey there,

I am trying to synchronize all the files from a back end server and https://infocon.org/cons/ It takes about an hour to run the synchronize pass, and it ends up to being a couple thousand files. I get the big menu of what files I want to sync / delete / etc. and when ready I click OK and immediately get the crash. If I start synchronizing directory by directory it doesn't seem to crash.

Good luck and thank you for the great tool!
