Best Apps for Cleaning Up Junk and Config Files on Linux?

I think the best approach might be to keep your personal files organized in your ~/Documents folder. This way, even if you have leftover junk in directories like ~/.config or ~/.cache, it won’t affect your important files. I don't really recommend using 'autoremove' as it can sometimes mess things up. Instead, focus on backing up what you really want to keep, and let the rest accumulate if needed. Tools like 'FreeFileSync' can help you set up rules for what you keep. As for backups, I use 'timeshift' to create system snapshots. It’s a great way to recover if something goes wrong without having to go through every little file.

While there may not be a specific app for this, if you're on a Debian-based system, you can use commands like 'apt purge packagename' and 'apt autoremove' to clean up a lot of the leftover config files and dependencies from uninstalled software.
