Air Explorer vs davfs2

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.
