I have a lot of these files that I assume are backups of old projects I deleted. Does anyone know how to delete them?
I've tried every possible way, command prompt, advanced settings, file explorer. I'm on windows 10 and need help.

.BAK files are as you guessed backup-files.
They are complete normal files, and should be possible to delete from explorer. If they are not, then you have specially rigid windows-settings. I recommend you to log in as administrator, and fix that, but your issue is not with LMMS, it is with windows.

Besides that, since you are new in Forum

"Finally"
Noo! You are not supposed to delete .BAK files unless you have finished your project 100%.
BAK-files are one of the 2 safe-guards against loosing work, that is there for your sake!
Read about project-safeguards and recovery:
https://docs.lmms.io/user-manual/4-production/4.1

If you edit your project and save it a bak file will be created again.
You can delete bak files and nothing goes wrong. Calm down, musikbear. Sure, they're there as a safeguard, but they occupy space, or if you don't want the project what's the point of a backup?
You can disable bak-file saving behaviour in settings ("Create backup file" setting, NOT "Autosave," autosave is different). However, as musikbear has implied, this can actually be problematic- it is best to have a bak file in case something goes wrong. I would not recommend disabling backup OR autosave behaviour. It makes more sense to delete unnecessary intermediate backup files later, IF NEEDED.
But I sometimes make incremental versions of songs, like Joy1, Joy2, Joy3, etc. It doesn't make sense to have a backup file of each of them, especially if I want to delete some of the original project files, or if they're large.
If you delete a bak file before completing your project 100%, nothing will happen. I can confirm: I have never completed a project 100%, I have deleted bak files, nothing's exploded in my face (yet). Avoid deleting backup files unless you have a genuinely good reason, but there's no sensible reason to keep around bak files of incremental versions of ancient projects.
