Users often need to back them up. Backup systems often include Documents by default but not AppData.

Files in AppData are hidden, and you would not expect users to find them.

Further, many save games can be opened with a text editor just fine :)

My witcher saves were 10GB, until I realize that problem and deleted them, no wounder backups were slow. Skyrim is not that far off.

Pretty sure backup is already integrated in steam for these two games.

In the witcher 1 there is also an uncompressed BMP thumbnail with each save that is about a megabyte. It's PNG compressed in the witcher 2. They learned from their mistake.

Chrome's cache is in AppData/Local/Google/Chrome/User Data and Firefox's cache is in AppData/Local/Mozilla/Firefox/Profiles/. The only big offender on my system is npm with a cache in AppData/Roaming/npm-cache

Finding the directory requires new APIs introduced in Vista and Server 2008. See SHGetKnownFolderPath

I just tried to use the API. I literally couldn't find a working example on the internet in 2 hours so I guess noone figured it out in a decade.

I'm surprised that these new IsWindows...() functions claim compatibility down to Windows 2000. Doubt microsoft knew how they would name their next release 20 years ago. A Google search indicates that they are in fact broken.

If IsWindows... doesn't work then you can use the VerifyVersionInfo function directly.

I don't even get what you want to say.
