Does winscp3 have CRC checking

How does WinSCP3 guarantee that the file being transferred in not corrupted while in flight. Is there integrity checking that is occurring on the fly?

SSH protocol have built in integrity checking, hence file cannot be corrupted while transferred.

SFTP checksum bug fix?

I noticed the following bug fix in the history:

Bug fix: Checksum calculation with SFTP protocol was not working at all.

Two questions:
1. When running in batch mode am I use SCP SFTP mode?
2. Was this error present in 3.8.2?

Thanks

This is unrelated to your first question. There was a bug in file checksum calculation that can be requested from Properties dialog. This has nothing to do with SSH session integrity checking.

Depends on your settings.

2. Was this error present in 3.8.2?
The feature mentioned above was added in 4.0 beta.

CRC vs SSH

While SSH guarantees that all packages sent are accurate, it does not guarantee that the entire file was sent. That's why you still need CRC.
