WinSCP stall on large folders with many files in it

I don't know whether this is actually a bug or just me trying to use WinSCP for something it isn't made for.

I have a folder on my local system that I want to partly transfer to a remote server. However everytime I try to open the folder WinSCP goes non-responding. I have tried to wait 10 minutes but no luck.

The folder is big it contains about 600k files totalling around 4 TB, so it is understandable it takes a bit to open the folder, but it seems like this completely freezes WinSCP.

Is this expected?

Thanks for your report.

Can you send me an email, so I can send you back a debug version of WinSCP to track the problem? Please include a link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.
