I’ve had similar worries, especially when figuring out how to move files from one dropbox account to another
https://mac.eltima.com/transfer-file...pbox-accounts/ without exposing anything along the way. It let me handle both accounts through one interface and keep everything encrypted locally before transferring. That client-side encryption piece was the main reason I switched — it gave me more confidence that nothing leaves my machine unprotected. Definitely worth looking into if you want both security and convenience.
