After click on report-button, winscp closed and nothing happen, so I report this here.

Thanks for your report. How many files are there in the directories you are synchronizing?

That folder I want synchronize have thousands of sub-folders and thousands of files in many of this folders. Maybe I have forget to uncheck option for preview window? In case of too many files, maybe a summary instead a list of each file will be useful.

I run another comparing and its calculate comparing since 6 hours. ;)

OK, so millions of files in total?

In my case here are to compare/syncronize: ~3.5 millions of files in ~500.000 folders and have a size of 370 GB.

Hi Martin,

I'm also running into same Out of memory issue and the files that i'm trying to move are 7.1 Million records (approx 6 tera byte). Is there any fix for this issue?

Please help us improving WinSCP by reporting the error on WinSCP support forum.
