Can you give us step-by-step instructions to reproducing the problem?
Do you remotely login while WinSCP is running? Does WinSCP keep the large icons even after you close it and start it while logged in locally?

Sorry, I must have missed your post somehow.
What version of WinSCP are you using?
What is your screen setup? Do you have multiple monitors? What scale do you have set for your monitor(s)?

Anyone can help me on icon size?

Hi,
it is Commander interface, here a screenshot

What interface? Commander or Explorer? Can you post a screenshot?

Hi,
I now have large icons into my interface (I don't know what I've pressed obviously)...
How can I turn into small icons as windows do?
Thanks,
Chris
