What is the /mnt/us/system folder and what can be removed ?

HenriHenry · Today, 07:01 AM

On my (jailbroken) Paperwhite 6, the system folder is over 1gb, mainly because of the logbackup*.txt.gz which keep appearing (each over 100mb). Can I remove these safely ? How can I keep new ones from getting created ? (maybe, just maybe, it might come from the file manager I use on kindle, ncdu (found on the discord) ?)
I'm also wondering if the system folder has any use or if I can just delete it, and I have the same question about the browser_bellatrix something .core (found in /mnt/us, maybe it's because of the kindle browser patch)
Any answer would be appreciated, thanks !

Some general knowledge, the logbackups folder can be deleted in system folder, any .core or core related file like dump etc can be deleted

These are generally req only if you are diagnosing the problem like why Kindle or some sub process like wifi crashed(core files)

And logs are literally logs... backups infact u can always wipe them but remember if something breaks you can't diagnose it, so I suggest leaving 7days logs backups
