She doesn't even look at them most likely

Absolutely nothing, other than maybe her questioning my data storage habits as it's all trash.

Not really much. Now if my wife would get the dump the story might be a bit different.

Dies of boredom

My wife would probably try to have sex with her.

I don't think much would happen if my girlfriend or my wife had access to my files.

I have a 40tb NAS that I store most of my /home directory on, so I can share it between my desktop/laptop/steam deck. The only local files are coding projects, games, or device specific configs. My wife has access to all of it, and has never said anything.

I wouldn't be worried about the files but more about my wife finding out that I have a girlfriend.

"Why do you take so many goddamn pictures of our cat?"

"Why wouldn't I?"

She’d probably ask my why I have full archives of a lot of old websites, and why I have archives of everything I have ever written for school or work.

RPG books. So many RPG books.

Hypothetical Girlfriend would probably wonder why everything is so disorganized.

Either she is nerdy AF, at which point I am going to get silly and probably scare her off, or she is going to be extremely bored hopefully she gets the hint and that will scare her off.

Girlfriend works at the NSA.

You good bro?

Blink three times if you need help.

The only encrypted file I have is my kdbx.

I get excited that I have a girlfriend. Although I don't know what she wants with my game saves. 🤷🏻‍♂️

She tells me how intensly geek and boring my life is, before asking me to fix something on her computer.

A great deal of confusion, I imagine. I don't have a girlfriend, and since I rarely even leave the house on my own, I doubt my wife would believe that I do.

Nothing. She has no time to read Excel spreadsheets.

Depends. Does she know about my wife and kids?
