ExpanDrive vs VHD Attach

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.

VHD Attach is a free Windows utility for attaching and detaching virtual disks. It adds Attach and Detach choices to the right-click menu for VHD files, and options can add a Detach choice to the hard-drive context menu. The program can attach virtual disks automatically when the system starts in full-access or read-only mode, and it can display disk information without attaching the disk. It supports Windows 7, Windows Server 2008 R2 and later, including Windows 10; older systems such as Windows Vista are not supported. On Windows 8 and Windows Server 8, it can also be used with ISO images and VHDX disks. Command-line parameters include /attach, /detach and /detachdrive.

Automatic attachment of a BitLocker-enabled drive does not show its password prompt because mounting starts before the user interface appears.
