Sync issues Memes

Cloud storage providers have this special talent for backing up literally everything on your machine—your node_modules folder, your .git directory, that 47GB folder of Docker images you forgot about, your entire Steam library somehow. You're just trying to sync your Documents folder and suddenly OneDrive is like "cool, I found 62,387 items including your entire Windows System32 folder, that'll be $9.99/month for more storage." The selective sync settings are buried seventeen menus deep, and even when you uncheck folders, they mysteriously reappear after the next update. It's like playing whack-a-mole with your backup settings while your storage quota slowly dies.
