Can I delete KSP_Data directory?

[Nightside]

Will I break the game if I delete Can I delete KSP_Data directory, if I only play in x64?

I have several installs of KSP and that directory takes up a lot of space.

Yes, in fact you can do that, along with some other useless files/folders (buildID.txt, Launcher_Data, Launcher.exe). IIRC you can even rename the "KSP_x64.exe" and "KSP_x64_Data" to just "KSP.exe" and "KSP_Data" (like the x86 counterparts).

This is the first file CKAN looks for to determine which game version is installed (falling back to parsing readme.txt). It's smaller than 100 bytes, so deleting it to save space isn't what I would call a good trade-off.

(Yes, I know not everyone uses CKAN and you weren't necessarily recommending deletion, but I want to get this on the record before we start receiving problem reports from overzealous deleters.)

If you're already coding in looking for a fallback... why not the more obvious buildID64.txt...?

Fair point, I forgot that file. Luckily the logic already checks both.

The point about potentially corrupting data to save <100 bytes is not diminished.
