peers.dat & fee_estimates.dat ?

[OmegaStarScream]

I was checking folder and cleaning my PC till I find those couple of files called peers.dat & fee_estimates.dat , they was on D disk so it's not by default as it should be on AppData if it was created by an application . I'm pretty sure that they are not renamed or anything so anyone knows those files belong to what wallet exactly because I want to check them out if there is anything important

peers.dat [Versions v0.7.0 and later]
Storage for peer information to make a reconnect easier. This file uses a bitcoin-specific file format, unrelated to any database system[1].

fee_estimates.dat [Versions v0.10.0 and later]
Statistics used to estimate fees and priorities. Saved just before program shutdown, and read in at startup.

Basically it's useless and there is nothing to do with them really and it's for Bitcoin Core ? still can't figure why they are on my D disk though . anyway thanks Amph appreciate it
