Air Explorer vs ExpanDrive

Air Explorer manages cloud storage accounts through one interface for transfers, synchronization and encryption. It can move files directly between cloud services without saving them locally; the home page says transfers have no data limits. Listed services include Google Drive, OneDrive, Dropbox, S3, SFTP, WebDAV and SharePoint. The desktop app supports scheduled synchronization and backups, including mirror and bidirectional modes. Files and filenames can be encrypted before upload, and the site says they are unreadable without the password. Its Android app handles cloud and device files, synchronization, encryption and access to computer files added as a cloud. Free BASIC costs nothing and limits users to one account per cloud, read-only cloud transfers and synchronization, plus two simultaneous downloads and two uploads. Pro starts at $21 a year for one device; a two-year plan is $31 a year, and a lifetime license is $42 as a one-time purchase. Supported platforms are Windows, macOS and Android.

ExpanDrive mounts cloud storage and protocol endpoints as desktop drives, letting you access files through Finder, Explorer, and other applications. Files stream on demand rather than syncing folders, with local caching and an option to pin files for offline access. Listed connections include Amazon S3, Backblaze B2, Box, Dropbox, Google Drive, OneDrive, SharePoint, Nextcloud, FTP, SFTP, WebDAV, and others. It runs on macOS, Windows, and Linux. Server Edition can operate as a headless service on Windows Server and Linux, expose mounted storage as a Windows SMB share, and includes a command line for managing mounts and connections. ExpanDrive says connections use TLS and credentials are kept in the local operating system credential store. Plain FTP sends credentials and file contents in the clear; FTPS or SFTP is recommended for sensitive connections. The Free plan is free, billed forever. Business is $29 a month, billed monthly; Enterprise pricing is custom.
