I know how to reproduce the problem or the problem happens frequently enough. I wish to be contacted by the WinSCP team to help resolving the problem.

Thanks for your report.
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.

I'm trying to sync a folder with huge number of files (so I expect it to be slow but not to crash).
The folder is sub-divided into 100 subfolders containing each up to 50K files.
I disabled the 'preview changes' on purpose (see attached screenshot for options) hoping it would reduce memory requirements by allowing the program to process files incrementally - I obviously don't want to review changes on that many files anyway.

By the way, I also have the impression that even though I checked the option 'Use same options next time' and confirm overriding the direction to 'local' in the next dialog, the next sync direction is always taken based on the active panel, not on my previous selection.

I take the opportunity to thank you for the great product!

I'm afraid that it is too much for WinSCP.

All I do is synchronize. When I have a lot of things to synchronize, it does that and never works. Happens only since latest release.
