I have added `KLU.jl` package and it is installed in `C:\Users\path\.julia\packages\KLU`. However, I could not find in the folder the original C source codes of the solver, for instance `klu_analyze.c` as in [KLU](https://github.com/DrTimothyAldenDavis/SuiteSparse/tree/dev/KLU/Source)

It’s in SuiteSparse.jl’s binaries

So, will there be a folder called `SuiteSparse` on my hard disk which includes the binaries?

This is the package registry definition for version control handling.

That’s where the compiled jll package should be. And I believe the binary should be found in there.

I found two folders `ME9At_AXkrN.ji` and `ME9At_GdcRR.ji`. Are they?

`.ji`s are the compiled package code. But the package itself should also have the binary. Check artifacts.jl for suitesparse or klu
