If only everyone actually kept up with Windows development best practices, including Microsoft teams themselves[0].

Configuration via XML files, AppData, registry free COM activation, MSI installers, only to quote a few examples, are decades old by now, at very least since Windows XP.

[0] - To be fair, nowadays many young employees seem to only ever used Windows after joining Microsoft, so what else can we expect, if apparently they don't get the right mentoring.

I cannot stand AppData, specifically the way it's often used to store files that should be in Documents.

[jeroenhd]

That should be covered by the part about "best practices".

That said, I keep finding more AppData files in my Documents folders than the other way around. Linux software (especially legacy software that doesn't respect the XDG spec) is the worst for that, somehow spreading files and directories across my user profile directory and my documents directory.

Probably just preference but I hate when apps put things in the documents folder, thats where I want to put the things I've created specifically, not automated config files etc. There should be a 'Preferences' folder or something to separate the chod in AppData from the useful stuff.

I'd never heard of AppData until a few years ago when I went hunting for where some game config file was getting written to.

Seemed like a bunch of disparate things with the most common probably being a dumping ground for programming language library caches (Maven and NuGet and maybe another couple).

I lost my kid's minecraft world because it stored everything under AppData/Local or some nonsense.

[mattl]

How did you lose it? That sounds super frustrating

[kibibu]

By backing up everything in important-looking folders (including My Documents, My Games, the Minecraft installation folder), and overlooking AppData as it is 99% download caches, tempfiles, and other garbage.

[hobs]

:) and local state, configuration, and anything an app needs when you do stuff. It's really the local user state in most cases, very important to back up!

I made a similar mistake when upgrading my SSD. There was some token that was stored in there that I needed, and IIRC I had lost the password needed to generate a new token. I only realized that I was even missing it a few weeks later when I needed to use the tool again. luckily I still had the old SSD so nothing happened. This happened even though I'm familiar with locallappdata and have even used it in some apps I created. It's just not the first thing you would think about when doing a backup unless you've already been bit by it before. Apps generally don't tell you if they store something important there, and the tool I was using never tell me where the token was stored. Doesn't help that file explorer hides the folder from you by default.

Which programs do that? Or do you think things like preferences for programs should live among your documents?

[Gracana]

A lot of games store save files in appdata. That’s the only thing I (not op) can think of, and one I regularly find annoying (if only slightly).

[Suppafly]

Yeah I suppose that's the only example I can think of, I noticed a comment later mentioning that that is where minecraft saves things, although I'm not sure I'd want those in with my documents either. They probably should live some place that the user has access to, so I guess that leaves app data or documents, neither feels like a great choice.

[pjmlp]

It is not meant for that, rather blame the developers.

[CLiED]

Is there a book or site documenting these best practices somewhere? I'm getting into windows dev and am curious about them.
