I heard "crack open" (by clicking an icon) in a computer video course. When I googled it, it says roughly that "crack open" means "open". My question is: why not use "open" instead. I'm struggling with English phrasal verbs for many years without any improvement. In french (my semi-native language) economy in words is considered elegant and I can't understand the heavy use of phrasal verbs in English, especially when it seems not justified.
To crack something means to break something. In "crack open", the word is just acting as an auxiliary verb to show how something has been opened.
For example, if I said "I opened the door" you'd imagine I'd used the handle and opened it the normal way. But I could say "I kicked open the door", and now you understand that I forcibly opened it by kicking it.
To 'crack open' something suggests breaking it to get inside. You could crack open an egg, for example.
However, you will find native speakers use 'crack open' in a less literal sense to suggest opening something in a very rough manner, for example, "let's crack open a case of beer". I've also seen a lot of explainer videos on YouTube showing how to repair tech where the creator has said things like "let's crack open this phone..". It gives an air of casual confidence that helps to make what they are doing sound easy.
You can use crack open a computer in the right situation.
If a new computer (or phone, or whatever) comes out and you want to make a video about it, you can say something like "Let's crack this open and see what's inside". In this case, the "crack open" part refers to the fact that you are doing something outside the bounds of the normal use of the computer.
You can open a door a crack (i.e., just open it a bit). As a result, you may hear someone say (in Canada or the US, maybe elsewhere): Crack open the door and let some fresh air in"
And as @astralbee mentioned, you can crack open a beer (or a case of beer). It's not necessarily in a rough manner, it may be "boy, that was a long week, let's crack open a couple of beer and forget it happened"
