Even got an A in it. But today I learned that although Win10 appears to automatically open zip files when you click on them it doesn't work on everything.
Actually, that behaviour has been in Windows since (at least) Windows XP. The Explorer "opens" the file, which works fine for simple viewing of pictures etc. But if you actually want do so something more complex with the content, you'll have to extract it first, or copy/paste it from the "opened" view, or use a third party tool. I've been using 7Zip for many years, which opens Zip, Rar, 7z and several other formats.
By the way, I've been in software engineering myself too, graduated in computer science 1997. No Fortran, but we did get Cobol, Pascal, C++ etc
I've always kept my knowledge up-to-date. One cannot master all tech in detail, but it is enough to know that tech exists and when to use it. You can then master it on a need-to-know basis. And with Windows, I always make sure to know in-depth of all new features in a release, to make sure I use it as efficiently as possible.
