Duplicate files · Duplicates in cloud accounts
Are my cloud accounts checked for duplicates in the background?
Short answer: Yes, when that account's Auto-scan switch is on (the default). Background checks wait for a short pause in your typing, run one account at a time, at most once every few hours each, and pause on low battery or Low Power Mode.
Yes, if Auto-scan is on for that account — each account has its own switch, on by default. Background checks wait for a short pause in your typing, run on battery unless it's low or Low Power Mode is on, go one account at a time, and run at most once every few hours per account.
To check an account only when you ask, select it and switch Auto-scan off, then use Scan now whenever you like.
