Hi Martin
global change for all session works fine.
I Think FontHeight is the good keyword for specifics change. I'll try later if need.
thanks for your useful answer

If you want to change font size for all your session, change the PuTTY defaults ("Default Settings" saved session):

If you want to change font size for specific WinSCP sessions, see PuTTY terminal settings:

Hello,
I use winscp on window 10 pro with putty (rev up to date).

Is there a way to tell winscp to force the font size on the putty opened session

I don't want to creat a specifique putty config for each machine.

I want to use the winscp automatique created temporary session, whish should be able to force a font size.

I didn't find any spécifiques params for this on the winscp session config.

I tryed to pass a putty cmd line option (-fn "Monospace 12" for exemple) in the winscp session param environnement/putty parametres.

but it seams that the windows version of putty didn't recognize the -fn param (it works fine on linux version) I tried it on power shell. -> "cmdline Error"

anybody know a way to avoyd me to create a new putty session for each winscp session ?
regards,
