What 4Sync is
4Sync stores and synchronizes files across Windows, macOS, iOS, and Android, keeping photos, music, videos, and other files available online. It advertises 1 TB of storage and a maximum upload size of 20 GB. Synchronization carries updates between devices and creates backup copies, while file versioning keeps earlier versions available. Shared folders can be private for invited users or public through a link, with view-only or upload-and-edit permissions; password protection is also described. The service initially provides 100 GB of monthly traffic, with extra traffic available for purchase. A free plan and a 60-day trial are listed. The Premium plan costs $8.25 a month, billed monthly, and includes 1 TB storage with the 20 GB upload limit. Help pages cover account verification, password recovery, uploading, downloading, and sharing. The service is designed for people aged 18 and older.
