It does if you're using
-criteria=size

Well, if your server does not support setting timestamp of remote file, synchronization with WinSCP won't work. It does not make much sense to synchronize files, if you do not end up with the same timestamps on both sides.

Synchronize fails even though Ignore Permission Errors is Set to On. This occurs for both the GUI and WINSCP.com. I was attempting to synchronize files to a remote server and was receiving the following error...

The server does not support the operation.
Error code: 8
Error message from server: SSHServerAPI.SFTP.fxp_attrs
Request code: 9

I am able to put the files using both the GUI and WinSCP.com with the -nopermissions and -nopreservetime parameters.

I am currently using WINSCP version 4.3.6. I have also set the Transfer Settings to the following...

Upload Options

* Set Permissions = Not checked
* Ignored Permission Errors = checked (but grayed out)
* Clear Archive attribute = unchecked


Common Options
* Preserve Timestamp = unchecked
* Calculate Total Size = unchecked

Filename Modification

File Name modifications = No change


The following is an excerpt from the WINSCP.com log. I noticed the PrTime: Yes is set. I inserted asterisks for security purposes...
