Absolutely not, thank you. I don't mind it remembering what state it was in when it was last closed and reopening to that, but never never start maximized by default.

Maybe we could then take an opportunity to merge the work done by 7-Zip ZStandard fork. There are great encoders there - for example the underappreciated Brotli, with crazy results with compression or decompression time to compression ratio - it's been selected as a new compression algorithm for PDF, for example. https://pdfa.org/brotli-compression-coming-to-pdf/ Brotli is also supported as the compression for HTML traffic for a long time.
It doesn't beat LZMA2 in terms of compression ratio, but it's good to have a choice.
And there are those venerable LZ4 and ZStandard for those who may need them...
Thanks in advance.

I would like to suggest that HH:mm:ss should be the default in the "Date Modified" and "Date Created". Please see attached screenshot.
Or at least, make it possible for users to set it as default.
Currently, it is not comfortable to go through the View menu each time I want to display the seconds in those columns.
Thank you.

That worked, thanks!
Thanks for the new build. I hope you dont mind some suggestions:
1 - Make 7zip always start maximized.
2 - Make all colums of the GUI auto-resize themselves to fit.
Absolutely not, thank you. I don't mind it remembering what state it was in when it was last closed and reopening to that, but never never start maximized by default.

Hi Igor,
I would like to suggest that HH:mm:ss should be the default in the "Date Modified" and "Date Created". Please see attached screenshot.
Or at least, make it possible for users to set it as default.
Currently, it is not comfortable to go through the View menu each time I want to display the seconds in those columns.
Thank you.
same here, it would be better to let user set the default datetime format
