How to increase the line spacing

How to increase the line spacing

I'll look into this.
In general, it's better to set Windows text size globally.

I have added this issue to the tracker:
Issue 2172 – Directory tree does not adjust line height to custom panel font size

I'm sending you an email with a development version of WinSCP to the address you have used to register on this forum.

See also I cannot read the file panel font. How can I make the panel font bigger?

Thank you very much
