Also curious why every comment mentions just the number of rows as the only factor that matters. A 100M rows table of 3 integer columns is quite different from 50+ columns, 5 of which are text up to a few MB long.
What gets me is that even if you don't code much, if you're using a spreadsheet with formulas, in that moment you are writing code, and doing so in an awful, awful language. Sure, "SUM" is easy, but the moment you have any kind of conditional logic it gets pretty hairy. Maybe there's something about traditional spreadsheet languages that makes them easier than, say, numpy for non-coders, but I don't see it.
That's one of the reasons we started building Quadratic, it's a spreadsheet where everyone - technical or not can work with data in the same place. With our AI integration, anyone can start writing JS or Python for complex analysis or mix in formulas for simpler computations.
I really don't remember well, long long time ago in Window (XP?) either you can select multiple folders and zip each of them separately and/or you can select multiple zip files and extract them to separate folders within a single context menu
