.indexes & .tesnet3 not located on my Bitcoin dir
but i didnt modify the .conf at all since it should be by default with the latest version...


There is no default bitcoin.conf file nor is txindex enabled by default.

Without enabling txindex in the bitcoin.conf file, the indexes folder will not be created as the txindex is not being created.

There won't be a testnet3 folder if you are not running it in testnet mode.


  Well, tbh im not using it either on testnet nor mainet,


The default is mainnet. Mainnet is not a different special mode. Furthermore, "the blockchain" is tied to a network. It is not a shared blockchain between testnet and mainnet.

If you have not modified the bitcoin.conf file or started bitcoind with special options, you are using mainnet without the transaction index, so neither the testnet3 folder nor the indexes folder will appear.
