Reduce disk space

Hi, I have a small problem after installing the Cinders mod, which has nothing to do with the mod itself, but rather with the extractor.

I used UXM like everyone else, but the problem is that the game folder is now 54 GB.

​

So what I want to find out is if there's a way to reduce the size without breaking anything. The only mod I have installed is Cinders, and I'm aware it's large, but not this large. I know it has to do with what UXM extracted, but I don't want to touch anything unusual and break it.

UXM has the option to unpack, patch, and restore. If I click "restore," does the file repack everything but with the files I edited, or does it restore the backup?
