Dropbox is a cloud storage and file-sync service with automatic sync, sharing and version history, from a 2 GB free plan up to a $24/seat/month Advanced plan.
Keep it if You need reliable cross-device file sync and sharing for yourself or a small team, with built-in PDF editing and AI search.
Look elsewhere if You want to stay on the free plan for a real storage need, since 2 GB is too small for regular use.
