@risalmin: The command is available in the menu.
If you are willing to help me solving the actual column size problem: Can you send me an email, so I can send you back a debug version of WinSCP to track the problem? Please include a link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.

Also, quite a lot of people do not have a numeric keypad...

@ptha: Yes, that's what I've meant by Grey +. From the times those keys were (darker) grey on the keyboards. I've edited it to say Num +, as that is clearer (and it's actually what WinSCP GUI will display).

Just an FYI, for the Ctrl + + key shortcut, for the + I needed to use the plus key on the numeric keyboard.
Nothing happened when I selected the plus key to the left of backspace. This was in Windows 11/WinSCP 6.1.

Any chance of having autosized columns with remaining space added to first (name) column?

All Windows list views support Ctrl+Num + keyboard shortcut to automatically size all its columns. The next version will only add a command to the menu as a way to hint the keyboard shortcut to those who doesn't know it:
Issue 2196 – Automatically size file panel columns

@moped: Thanks for your report.
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.

Hello Martin,

I've sent you an email with the request for the debug version.

I'm having basically the same issue. Columns are "somehow" sized to a specific window size, but when it's moved to another screen with 125% scaling, columns are too wide, then again when I move it back, there is a lot of empty space after last column.

Any chance of having autosized columns with remaining space added to first (name) column?
