It happened to me once, disabled cloud backup on my documents folder, and onedrive decided if it can’t have my folder, no one can
I did get my data back, since onedrive kept it in the rubbish bin or somewhere like that
After that i nuked onedrive from my laptop, and now i use arch btw
It could fit in a standard 3.5 inch floppy disk, sure it’s not the smallest, but for a full app written in javascript and not asm it is, in fact, small
