So i know and have noticed that the Cydia apps settings are somehow saved on your device, even thou u have uninstalled the original app itself. Is there any way to delete those files, preferably with iFile?
Why would you want to?
They're only a few KB's worth of data, I'd leave them alone.
You start deleting stuff with ifile and one bad delete and you will be stuck having to restore.

Each app and each developer saved their data on different places/formats/ways, if you really need/want to get rid of them, you need to go to the developers website and ask there (or you can tell us which app here and take a chance to see if anyone here know the locations), there is "no" a default location where these type of data is stored.
However as AJ already said, going in and erasing stuff with iFile is NOT recommended
