Any reason to keep encrypted Wii U game files?

[jtabc123456]

I noticed Wii U Downloader implies the decrypted files are for use with Cemu and encrypted are for use with a Wii U console.

Does this mean you cannot install the decrypted files on the Wii U? Is it possible to encrypt the decrypted files (is there a program that does this)?

Basically, for a long-term local backup, I'd like to store the game files exactly once, ideally decrypted since they can be compressed. But I don't want to lose functionality by keeping them in the wrong format (potentially losing the ability to install on an actual console, as implied in the screenshot above).

As you saw in the screenshot, encrypted (clean WUP/.app format) is what you need for installing and using on a Wii U proper, so if you want to keep functionality intact, you need to keep them encrypted.

While I am familiar with tools to decrypt these files, I don't know of any tools to then encrypt them again sadly.

Counter-intuitive but
decrypted files=loadiine, outdated WiiU mod era products, you need to place files on sd=slow read/write compared to usb, difficult DLC setup, of course these are irrelevant on cemu/emulators
encrypted files=normal eshop game install process+ticket handling, so go for this if you play mostly on physical WiiU.
