The built-in FTP client supports explicit TLS/SSL (FTPS) and SFTP (SSH File Transfer Protocol). Version 4.2.10 also supports connections to Amazon S3 and Microsoft Azure, though newer authentication methods (like Azure Managed Identity) require later versions.

The folder comparison engine in 4.2.10 allows you to compare local folders, network drives, and FTP servers side-by-side with color-coded syntax. You can filter by timestamp, size, or content (CRC or binary comparison). The legendary "Mirror" function ensures one drive becomes an exact replica of another—invaluable for backups.

Version 4.2.10 introduced a refined Table Compare session type. It can read raw CSV files or leverage Excel’s COM interface to open .xlsx files. You can freeze header rows, sort columns on the fly, and copy entire misaligned rows with a single keystroke. This is a killer feature for data analysts reconciling database exports.

If you decide to move past 4.2.10, Scooter Software provides a smooth upgrade path. Your license key for v4.x works on future v4 release (including 4.3, 4.4, up to the hypothetical 4.9).
